Glacial Sync Speeds

[Baraqyal]

Hey guys,

 

Been using btsync for a while and it's always been a bit sluggish for me. So I finally decided to do something about it and hopefully fix that.

 

I'm running the latest version (1.2.82), on two machines that are:

 

Locally - running Ubuntu 12.04.3

Remote - server running Gentoo

 

My connection is an ADSL2+ connection (20Mbps down / 1Mbps up roughly) located in Melbourne, AU

My remote machine is sitting in a data-centre with a 150Mbps port located in The Netherlands

 

For reference, I can max out this connection downloading via HTTP but Btsync is much nicer in that it's automated. Unfortunately using Btsync means I only get ~200KB/s (500 on a good night) while using HTTP means I can get at least 1MB/s off the server.

 

Here's the log:

[20140204 01:35:39.824] total physical memory 536870912 max disk cache 2097152[20140204 01:35:39.824] Using IP address 10.1.1.12[20140204 01:35:39.824] Loading config file version 1.2.82[20140204 01:35:39.962] Loaded folder /mnt/raid/download/-snip-[20140204 01:35:39.986] Loaded folder /mnt/raid/download/-snip-[20140204 01:35:40.025] Loaded folder /mnt/raid/download/-snip-[20140204 01:35:40.146] Loaded folder /mnt/raid/download/-snip-[20140204 01:35:40.906] UPnP: Unable to get external IP.[20140204 01:35:40.935] UPnP: Device error "http://10.1.1.1:49152/description.xml": (-2) [20140204 01:36:17.856] UPnP: Device error "http://10.1.1.2:1990/WFADevice.xml": (-2) [20140204 01:36:17.864] UPnP: Device error "http://10.1.1.1:49152/description.xml": (-2) [20140204 01:36:17.889] UPnP: Unable to get external IP.[20140204 01:36:28.824] NAT-PMP: Unable to map port with NAT-PMP.-- lots of 'piece complete' notifications ---- more UPnP errors (same as above) ---- repeat ad infinitum --

So the .1 address is the modem, the .2 address is the access point.

 

I hope I've provided enough info. Any suggestions guys?

Well, from your log, it looks like there's a problem with UPnP on your router, and also given your devices are in two different locations (i.e. on two different LANS, as you've not indicated that you have a VPN between them?) it's most probably that Sync is making relayed connections (rather than direct connections) between your devices.

 

Relayed connections are generally a lot slower than direct connections (as they are "relayed" through an intermediary).

 

Therefore, to improve your transfer speed:

1. Resolve your router's UPnP issue(s)
2. Consider setting up a VPN between your two locations so that your two devices in different countries appear as though they are on the same physical LAN

I've resolved some of this. Seems the machine in question was reporting good WiFI signal strength but dropping packets. I've since resolved that and get much better speeds in BtSync and other apps.

 

Now it looks like I'm having the same issue as these guys: http://forum.bittorrent.com/topic/25217-inconsistent-speed/
