Thanks for following up on this thread. While I am not interested in alpha testing, I look forward to the release of version 1.4.

It's not as bad as syncing larger files. It is between 2 computers.

Sorry this took so long to post. Here is a graph of a few hundred 1.5MB files being synced between two peers:

The fast/slow pattern happens to me when syncing only two computers. I have tried setting up a Virtual Private Server through DigitalOcean and the problem still happens, so I doubt it's an ISP issue for me, too.

It looks like I was wrong about the version number that I had. I am actually using version 1.2.82. I have not had a chance to sync files that are 1.2MB yet. I will post a graph of this when I have a chance.

OK, thank you for clarifying this.

Thanks for maintaining this PPA. It makes installing BTSync on Ubuntu much easier! However, It seems that the version available in the PPA is 1.2.2.3. It seems that the current version available though the Bittorrent website is 1.2.82. Is there anyway to update the PPA, or am I wrong about the version numbers?

Sure thing, I'm glad to help! BTSync was installed on both computers from the tuxpoldo/btsync PPA. The two computers are as follows: Server 1: - Ubuntu 12.04 - 2GB RAM - 200GB Hard Drive - Virtual Private Server - Intel® Xeon® CPU X3440 @ 2.53GHz, 4 cores - 1 Gigabit up/down connection to internet - BTSync 1.2.2.2 - Static IP address Server 2: - Linux Mint 13 MATE - 2GB RAM - 250GB Hard Drive - Dedicated Server - Intel® Atom CPU N550 @ 1.50GHz, 4 cores - 40Mbps down/20Mbps up DSL residential internet connection - BTSync 1.2.2.2 - Dynamic public IP address - Server is behind a NAT (with a static private IP address) - Router is an ASUS RT-N66U running Tomato 1.28 firmware by Shibby - Port forwarding is enabled on the router for the port that BTSync uses I have also tried sharing a folder between Server 1 and a friend's computer running Windows on a different ISP. The bandwidth pattern seems to go up and down when transferring files between computers also (although I don't have a graph of that usage).

Below is a bandwidth graph of a sync over my LAN (with the lan_use_tcp enabled): Here is another sync over the WAN: Just to compare, here is a file copied via SCP (over the WAN) between the same two computers as above:

For the graph that I posted, the entire window represents 10 minutes. So, each vertical line would be about 2 minutes. I do not have a graph for the bandwidth usage pattern during a LAN sync. I will post one later today.

My setup is as follows: Server 1: Ubuntu 12.04 server on a symmetric Gigabit connection (I usually get about 500Mbps up/down). BTSync running Static IP address Server 2: Linux Mint on a DSL 40Mbps down/20Mbps up connection BTSync running Dynamic public IP address behind a NAT with a static private IP address BTSync has been assigned a specific port. Port forwarding rules have been set in the router for the specified port to the private IP address. I sync one folder between the two computers. When I add files to server 1, the files start downloading on server 2 (as expected). However, the download rate will fluctuate. It will seem to climb up to about 40Mbps, then drop to zero. This repeats until the sync is complete. I have a graph of this below. The file I synced in the graph below is about 300MB. I have tried setting a download limit on server 2, but this does not help. Is this normal behavior?
