  1. I have current version of Sync running on a Feral seedbox and on my home NAS (Asustor) through a R7000 router. Speeds will transfer in the neighborhood of 250 KB/s until I restart the Sync app on my NAS. Then I get 4-5 MB/s no problems, for a while, (not sure how long though.) I have tried to give the local address for the NAS priority "quality of service" on the router but have seen no improvement. Charter is my carrier, and I am not aware of them throttling, and the fact that it goes at faster speeds upon restarts makes me think it's not Charter... What do you think I can do to maintain the normal faster speeds? (Happy to give more details to try to troubleshoot this!) Thanks for any help, J
  2. Hi, I would like to do this thread to state the situation about speed and maybe ask a few questions to have clear answers. So, I have a reasonable semi pro setup on my LAN, carrier grade equipment + cat 5E at minimum UTP. several hosts, as NAS, LINUX servers, Xenserver, differents others hosts,... So what I obtain generally is between 30MB and 50 MB. I didn't change anything about the default settings. So the transfer are always encrypted. Since we can all agree that the max speed should be 110MB maybe there are reasons for our general speed. So I would like to ask, when the interface indicates a speed does that count the part of the encryption in it or is it the actual amount of real data transfered? if no, how much is the encryption taken on the network? what other things should we take in consideration? Since on my setup and any small company setup there would be certainly 3 or 5 hosts having all files so able to transfer every files asked, why shouldn't we be able to transfer at max speed of the LAN besides HDD problems of course which couldn't be more marginal than on a setup with several hosts?
  3. Hey, First off, please dont tell me to google or that there are a ton of posts like this one, most of those actually have slow transfer speeds but also local. not just over internet. thanks I've just started using Resilio and i like the functionality. I just have one question: How can i troubleshoot slow transfer speeds over the internet? When i sync things locally, i get around 20-30MB witch can be better but works good enough... But when i start to sync to a friend of mine over the internet, my speeds drop to about 300-500Kb... and not really stable speed... it changes all over the place. I'm not using a relay server so that is not the issue. Out internet connections are: 300/30 and 200/20 so that also is not a problem. When i transfer a file using filezilla(sftp) i have consistent speeds around the max of our internet lines. Also i would like to know what ports are used for the connecting part (when adding a new folder to sync). As i found out that i only can add folders between me and my friend in one way. If i add a folder my friend shared, it works. When i share the folder and my friend adds it, it just wont connect. This is a firewall issue as i'm using PfSense and my friend is using a normal router. As soon as connections come my way, there blocked but i can't seem to find the port number. In a log i found 35454 when a windows client tries to connect but forwarding this did not solve it. In the log it said: sending ping to <my remote ip>:35454. I know that PfSense blocks all pings for safety. so that might explain that. But adding folders from me to my friend seems to be a workaround for that. But as my router might be blocking more that just the pings... maybe opening ports can help? or is the slow transfer speed something else? What are your average transfer speeds? I also see in the log that files are split into small pieces... is it worth changing that value to something a bit bigger? maybe bigger pieces transfer faster as it doesn't need to setup a new connection for every piece?
  4. Dear Support, we have installed the demo license of resilio sync on two peers. the idea is to distribute prox. 80 media files of 60GB total on a daily basis so that only metadata has to be passed around afterwards and both facilities can work with the same footage. the setup process was straightforward but we are not getting any acceptable datarates. when transferring the footage via FTP we are getting around 8-10 megabytes per second, what would be perfectly fine. with the resilio sync client however we are seeing only 2,5 megabytes per second and after checking and tweaking all the bobs and whistles in the power user prefs and a brief check of our firewall config we are out of ideas how to get decent speed between the two peers. we checked with another peer without a firewall and only got 500 kilobyte per second there. if we could get rid of this limitation we would sign a subscription immediately as we are trying to build a decentralized workflow between multiple facilities but with datarates as low as this resilio is sadly no use to us... I've opend a support call from the application and submitted the profiler data of both peers already but until now i haven't heard back from you. Ticket is #52653 cheers Sebastian
  5. Hello. I have been using Resilio sync as a backup and file transfer solution for my private files, im very happy with the service. So happy i upgraded to Pro. BUT i have very slow sync speed, on lan. My tansferspeed seems to be capped at 1,1 MB/S it always hovers between 1 and 1,1MB/S Resilio Sync is running from a computer with linux as os. my internet Upload speed is About 1,25 MB/s so its no surprise that files being synced over internet are capped at arond 1,1 MB/s but i can't figure out why my LAN transfers are capped at that too. I have followed the advice pages and cant get any increase in Lan transfer speed out of them. My HDD Has Read/Write speed of about 35 MB/s. My Lan speed is 1 Gbps. UPnP ports for all devices running Resilio sync are forewarded Any help resloving this issue would be greatly appreciated.
  6. So just like the title says, most of the time BTsync maxs out my connection from my server but sometimes i get reduced to a crawl and I would like help diagnosing where the problem lies. My server has 1Gbps upload and my home connection has 100Mbps down. I have no idea what the problem is possibly BTSync settings, isp throttle at certain times, a bottleneck somewhere between me an d the server or my server not uploading at advertised speeds correctly. It has to be one of these four but im not sure how to diagnose it. Where can we start and what information can i provide to help us figure it out? Thanks
  7. I recently moved, and had no choice but Comcast as an ISP. I also have the task of syncing about 1TB of data from a client (All 4K Mov files over 200MB each) for a movie I'm doing Visual Effects for. We got him set up with BTsync, newest version (and myself) and he shared his folder with me as an owner. We are currently experiencing speeds of, at best, 64Kbps. His internet connection according to is about 60/30 (Fiber via Optimum in NY), and mine is 50/5 (Copper via Comcast in OR) I know Comcast is known to throttle bittorrent traffic. Would this also apply to btsync? In which case, I know to get around that you can enable protocol header encryption on most bittorrent clients. Can this be done in btsync? Anyone have any other ideas? I've check both of our computers and the listening port is correctly open. Neither of us have speed limits set in btsync itself. And neither of us has anything else running on the network. The only other thing I can think, is his computer is still indexing (started only about 20 minutes ago) maybe the speeds are just slow until indexing is completed, and I'm reacting too soon? I'm in the process of doing speed profiling, but with these large files it will take some time. Thanks for any help! EDIT: I tested some other files with other peers shares, and the speeds are fine. So I'm assuming the speed issue is on his end now. But one question I have is... I have a dedicated server that acts as a "cloud" server for many of my btsync syncs. However it only has about 290GB free, so I cant use it as a mirror for this particular share since it wouldnt all fit. But is there any other way I could make use of this dedicated box to help our speeds as a relay or something?
  8. Hi, I am trying to gauge whether I have a speed issue but the indicator doesn't seem to be transferring data very fast (or at all). I have seen it download at 150 kb/s / 350 kb/s but no longer getting any information - although I have reason to believe data is certainly being transferred - please see screengrab taken while download is going on. It shows files being transferred (History) while indicator showing 0.0 kb/s Shoud I be expecting faster than 350 kb/s anyway?
  9. I have had great success in the past, but am currently experiencing very slow download speed on Sync (Android) over my LAN! (6.4 kb/S max, it seems). I have one synced NAS attached via ethernet cable to router. I have 3 windows PCs synced connected via Wifi, all fully synced. In the past, I have had very good download speeds via Wifi to my android device (Dell Venue 8). I recently wanted to "reset" my sync so I erased the sdcard, uninstalled Sync, and reinstalled and reconnected Android Sync via QR code. Now my max download speed to the Android device is 6.4kB/s! Previous download speeds were up to 2MB/s. Where should I be looking to figure out where the bottleneck is?
  10. Hello, I am synchronizing a Debian server with a Synology NAS. It works but it is very slow (10KB/s). I am synchronizing 30 GB and the is about 50 files (300 MB/file). My NAS is behind a 15 Mega ADSL line and my server has a 1G fiber optic. If someone knows from where the problem come from. I am using btsync 2.0 on both. THank you
  11. Hey Guys - The Issue I've been using BTSync Pro for a few months now and enjoy it. For the past few weeks, I've had an issue where sync speed between a remote Linux host and my local PC hasn't been what it should. At top speed, the sync should be running at ~2Mbps but instead it hovers around 250-300Kbps. I attributed this to my OS as I had a couple of other issues. This weekend, I went to Windows 10. Not an upgrade, but secure erased my OS SSD, installed Windows 10 x64 Ent from scratch, and reinstalled everything. All app configurations were new, too no copying over any old AppData configs. Once I installed BTSync, I added it to my existing sync devices and set up my sync pair from the Linux box. Same issue is occuring. Workaround Found I did find one thing which has resolved it somewhat. If I leave a sync running at 200-300Kbps, it stays that way - however - if I pause it, wait a few seconds, then unpause it; it syncs at full speed. Doing this only works about 20% of the time, but when it does, you know it as the speed jumps to 2Mbps in a couple of seconds. The problem is that I sync files at all hours and it's constantly on and off. Therefore, it would be impossible for me to sit and watch it then perform this fix as needed. I'm 100% confident that no other transfers are going on at the same time as I've lived with this issue for a while now and done many tests. I will say that the Linux server is overseas, but if BTSync was working correctly or it was a connection issue, I'd think I'd see the speed fluctuate during sync, but it doesn't. It either stays at 200-350Kbps or at 2Mbps - never a speed between or back and forth between the two. Is this a known issue? Would you think it be more related to the network / internet or perhaps the Linux end? Any suggestions? Please help, Support, as I'm close to just setting up ownCloud locally and using it the same way. Thanks!
  12. Hey Guys - I've been using BTSync Pro (paid license) between multiple platforms for a couple of months now and love it... until recently. A primary sync I have is between my home Windows 8.1 system and a remote (over internet) Debian installation. 95% of the data transferred between the two is the Windows 8.1 system downloading from the Debian one. For the past couple of weeks, the download speed has been at ~250kb/s - much lower than the ~2mb/s which it ran at prior to this. Being a Systems Admin for years, I have tested a variety of things which make it seem to be due to BTSync / it's configuration, itself - not the connection or OS. Here are some things I've tried: - I've restarted both systems, my router/gateway, and cable modem - I can pause the sync, download via HTTP, HTTPS, and/or FTP at the ~2mb/s speed during these times, unpause the sync, and it still downloads at ~250kb/s. - I verified that the port specified in BTSync (54531) is open on the router - Verified I'm on the newest release - 2.0.128(36) - Run various other diagnostics verifying that the bandwidth isn't being used elsewhere (on router (use OpenWRT) and on OS) - Verified that BTSync's config wasn't set to limit speed The last thing to do would be an OS reinstall, but as I have a ton of things installed / hosted on the system and seeing as nothing else is having issues; it would be an all day event. Any suggestions? Thanks!
  13. Origionally posted this query in the BitTorrent Client section, as opposed to the BitTorrent Sync area. Can only hope I won't be flamed to harshly ... I'm getting the following Sync speeds on a GigaBit LAN Min 1.6 MBps Max 6.0 MBps Avg 2.3 - 3.8 MBps Would I be totally off-topic expecting around 125 MBps? (when there is no other traffic on the LAN) Specs: 2x i7 8GB 256SSD Windows 8.1 Laptops running Sync v 2.0.128(36) connected via CAT6 cabling to a NetGear R6300v2 NoteBook 1 - NoteBook 2 - Sync Settings uPnP port mapping enabled Receiving & Sending rates NOT enabled lan_encrypt_data false rate_limit_local_peers false
  14. Hello, is it possible introduce a panel that allows me to see the upload speed and download for each individual peers during the exchange of files? For now you can only see the total speed for all peers. Thanks Andrea
  15. Hi there. Following setup: - Macbook Pro with external USB 3.0 Hard drive - Cubox-I Freescale imx6 dualcore processor linux box running a debian version - Cubox-I is connected via 100mbit ethernet - Macbook pro is connected via 144 Mbit/s Wifi. - Both machines are on the same network - CPU load is not abnormal so that can't be the problem - I get a maximum af 160kbps when syncing. Mostly only around 60kbps Any ideas how to speed this up?
  16. What speed can one expect using BitTorrent sync? I set it up for a friend. He has 2 Win7 SP1 systems on a 802.11n wireless network. Syncing files between the 2 systems results in 3mbps transfer rates. Seems slow. Nothing else transmitting data on the network.
  17. I've been trying to get BT Sync to transfer files quickly between machines on my LAN ever since it was first made available. But speeds have been quite erratic. Finally I found a setup that is performing well, and I just thought I'd share it. Not sure how vital these changes were: I enabled "Use predefined hosts" on both machines, set "lan_encrypt_data" to False. (Both machines) What seemed to be vital to getting speeds up: finding the right values for "recv_buf_size" and "send_buf_size". With the defaults (10/10), it kept settling at ~1 MB/s. So I tried 32/32, but the improvement was minimal. I then tried out 24/24, and the results were dramatic: I started getting 6-10 MB/s. The particular values might be specific to my setup, but with experimentation I'm sure others can find their own "butter zone" values. The main lesson I learned that applied to BT Sync buffer size was: bigger isn't always better.
  18. Hi I use btsync in a small office with 3 peers on a 100mb/s LAN and a single peer on a separate off site backup machine at my house which is accessed over a the WAN via a 8mb/s connection (actually more like 0.2mb/s practical upload speed). We share documents locally using a synced folder, this is great and much better than dropbox because we don't have to wait for the file to upload to a server on the WAN before another user can access it. It's almost as good as having all documents accessed on a server but I can have my entire office on my laptop when I'm away. Except, sometimes, when there are a lot of files queued up for sync, a recently edited file seems to wait in a queue before it gets synced to LAN peers. This can take a long time if there are a lot of files queued to sync to the WAN peer. Is there any way I can configure btsync to prioritise syncs to fast peers over slow ones? Thanks W
  19. Hello, could somebody help me with the following issue: I have 3 Windows-based machines with the BT Sync 1.3.104 installed. A and В - offices in different countries C - hosted server at Serverloft. They share the same folder. What I noticed is that the transfer speed between A and B is much slower than between A and C, or B and C. So, it's 3-4 times faster to upload files from A to C (to a separate shared folder), then move them on C to another shared folder and then download them back from C to B (again with BTSync), than to transfer them from A to B directly. I guess it might be related with the type on Internet connection at offices or so. When it works between A and B the bandwidth is not fully utilized for somehow reason... Is it possible to configure BTSync so, that it doesn't try to sync A and B directly, but only via the C server? Thanks in advance, Nikolai.
  20. I have been using BitTorrent Sync for a while. I've tried many different cloud backup solutions (including several other peer-to-peer backup tools) and finally choose BitTorrent Sync and Dropbox as my cloud backup solutions. Generally speaking, BitTorrent Sync is fast once it starts to synchronize. However, I found quite often that BitTorrent Sync waits for a long time (about 5 to 6 minutes) to start synchronization. As BitTorrent Sync has no reliable way to show synchronization progress on Linux (don't trust the web UI) currently, it is very annoying for me as I constently use multiple computers at the same time. To address this issue, I even wrote a bash script to test whether a local file has been synchronized with the remote one. Dropbox on the contrast is much better on real-time synchronization. Changes on files in the Dropbox folder is almost immediately captured. I wonder whether BitTorrent Sync can do a better job to detect changes faster? Perhaps cache freqently changed files?
  21. Hi, I'm using the mac and linux version of BitTorrent Sync. I'm very excited about it! I was wondering if there was log file which printed out the transfer rate of the downloads. The mac version provides a brief glimpse of the transfer rate, but it is removed as soon as the upload/download finishes. Thanks!
  22. Hi, can some of you explain to me how a btsync client decides what upload bandwidth will be used to the other members sharing the same secret? Background: When my team (consisting of 5 clients) shares data over the internet we can see at the seeder client, the system with the lowest upload bandwidth gets the most bandwidth from the seeder. "iftop" is a nice tool to check this on a Linux client. We have here the effect while transferring large data files that the clients with the smallest upload capability get ready first and the systems with largest possible upload bandwidth finish at last and this in a strict order! This is obviously the wrong order since it would be of course optimal to fill the client with the highest upload capability first so this resource can be fully used while distributing the data instead of waiting for the clients with the smallest capability to upload data to the others. But perhaps this simply bases on the understanding of the algorithm used and can be influenced somehow, so that's why I'm asking this question, here. Greetings from Germany
  23. Hi there, Love the theory of this program, but having significant issues in performance. I have it set up where a few remote computers send files to a central computer with this program. Works good, but kills the internet in the process. The central computer would only be downloading at a reasonable rate (so no limited required). When in the process of even a single file, the ping rate to the internet jumps from 45-50ms to between 500-600ms. when doing speed tests during the transfer, the speed is crippled. Download rate drops 80% (even though the file download is only sucking 40kbs due to upload speeds on the other end), and the upload speed (even though there's no upload) drops to 0.02mbs... worse than dial-up. As soon as I close the program, ping rates return to 45-50ms, download/upload rates return to normal. It's scary. I manage the site remotely, and need to be able to administer it over the WAN... when this program runs, I can't even RDP without drops, and hosted webpages from the site drop as well. Any thoughts?
  24. So I recently moved to a new place and got a new ISP, specifically Comcast. I know they've been known to throttle, but I ran Glasnost after getting some pretty bursty download speeds (see graph...I don't know how to attach a screenshot so the picture is here: and it turned up nothing. I am going through a modem ( and a router ( and should be getting about 50Mbps, which is what I get for apps like Steam and the like. Any idea what could be causing these bursty and highly patterned speeds? Thanks
  25. I'm trying BTsync out on a local 100-1000 network for starters ... 1 desktop PC, one laptop and one Raspberry Pi. The setup works (on my LAN at least) ...but speed is disappointing... If I add a folder to the sync folder on the PC with 30 files at a total of 500Mib it takes just over 10 minutes to sync to the laptop (both are fast machines) ... seems very slow to me ... and I would have thought, that the distributed nature of torrent syncing would mean that the slow element in my network (the Raspberry Pi) would not slow down syncing between the other two ... Does this speed sound reasonable to you? Linux on PC: i7 @ 3.3Ghz with 16 gb RAM wired network, Laptop i5 @ 2.5 Ghz with 8gb Ram wireless, Raspberry Pi (v2) wired network, Router Asus RT-AC68U
