I have a Ubuntu Linux server running BT Sync version 1.3.94 and a Windows 8.1 client running the same version, 1.3.94. The Linux server is on a 100mbit connection and the Windows 8.1 client on a 20/5mbit connection. I can only get a maximum transfer of around 200KBps which is quite dismal seeing as though from the same server I can saturate my 20mbit connection through FTP. Here is an excerpt from the log on the Windows 8.1 client: [2014-05-06 21:42:17] Found peer for folder \\?\E:\BT Sync 003E6B87924ED9673AFA94F34958660294FDC2CF xxx:37523 direct:1 transport:3[2014-05-06 21:42:18] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:19] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:20] Going to sync state with peer xxx:37523 (003E6B87924ED9673AFA94F34958660294FDC2CF)[2014-05-06 21:42:20] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:20] Merge: generating intial request with root 9D9A3C89394433FA69703691551E26C40645067F[2014-05-06 21:42:20] Got id message from peer GibServer (003E6B87924ED9673AFA94F34958660294FDC2CF) 1.3.94[2014-05-06 21:42:20] Merge: processing root message, remote hash 9D9A3C89394433FA69703691551E26C40645067F, timediff: 47[2014-05-06 21:42:20] State sync finished for folder \\?\E:\BT Sync[2014-05-06 21:42:21] \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4: Piece 5 complete[2014-05-06 21:42:21] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:22] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:23] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:24] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:25] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:26] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:27] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:27] Send ping to peer (003E6B87924ED9673AFA94F34958660294FDC2CF) for share 637AF1123C6253AE430580620F7479F9AFE24BCD:[2014-05-06 21:42:27] ping xxx:37523[2014-05-06 21:42:27] Got ping (broadcast: 0) from peer xxx:37523 (003E6B87924ED9673AFA94F34958660294FDC2CF) for share 637AF1123C6253AE430580620F7479F9AFE24BCD[2014-05-06 21:42:27] Found peer for folder \\?\E:\BT Sync 003E6B87924ED9673AFA94F34958660294FDC2CF xxx:37523 direct:1 transport:3[2014-05-06 21:42:28] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:29] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:30] Going to sync state with peer xxx:37523 (003E6B87924ED9673AFA94F34958660294FDC2CF)[2014-05-06 21:42:30] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:30] Merge: generating intial request with root 9D9A3C89394433FA69703691551E26C40645067F[2014-05-06 21:42:30] Got id message from peer GibServer (003E6B87924ED9673AFA94F34958660294FDC2CF) 1.3.94[2014-05-06 21:42:30] Merge: processing root message, remote hash 9D9A3C89394433FA69703691551E26C40645067F, timediff: 47[2014-05-06 21:42:30] State sync finished for folder \\?\E:\BT Sync[2014-05-06 21:42:31] Torrent \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4 status:137 error:<NULL> meta:1 conns:1 io:0[2014-05-06 21:42:32] \\?\E:\BT Sync\Motorcycle Run 1 of 3.mp4: Piece 6 completeOn the Linux server, the log just states this over and over: [20140506 21:50:12.218] Incoming connection from xxx:63347[20140506 21:50:23.146] Incoming connection from xxx:63347[20140506 21:50:34.247] Incoming connection from xxx:63347[20140506 21:50:45.250] Incoming connection from xxx:63347[20140506 21:50:56.233] Incoming connection from xxx:63347[20140506 21:51:07.184] Incoming connection from xxx:63347[20140506 21:51:18.117] Incoming connection from xxx:63347[20140506 21:51:29.108] Incoming connection from xxx:63347[20140506 21:51:40.070] Incoming connection from xxx:63347I would love to know what could be configured incorrectly to create this scenario as I would love to use BT Sync for my videos, but with the current speeds it would take far too long.
