Readynas 6.1.7 Sync Speeds Are Incredibly Slow

Recommended Posts

I am running the BitTorrent Sync app (version 1.2.92; ARM) on my ReadyNAS (version 6.1.7) and the download speed is prohibitively slow. I've left it running overnight and It's been averaging about 50kB/s. It's currently connected to 3 computers on the local network (gigabit connection), all of which have full copies of the sync folder. Those computers are running Windows and OSX.

 

I've noticed that CPU usage is quite high while syncing, with the load average hovering around 3.9 (nothing else is using any noticeable amount of CPU). I disabled the antivirus scanning on the box, which helped a little bit due to less CPU overhead, but not much.

 

I've tried upgrading to the latest btsync version, 1.3.87, but this did not solve the problem. It actually seemed to cause more issues as the web interface would go unresponsive for long periods of time. Using Transmission to download a torrent over the internet, I reached speeds up to 3MB/s without a problem.

 

Anyone have any ideas? Here are the logs.

@meltingice,

 

Though the log is not set to maximum output, it is still swarming with 2 kind of messages:

1) one complains about communications with sqlite DB (so I suggest checking that the user running btsync has permissions to access storage folder)

2) another says that remote peer is connected but actually does not pick any blocks to download for pretty long time. 

 

I suggest collecting full debug logs from 2 peers so I can get a better picture of what is happening.

Yep, the main problem was the file permissions. The default .sync folder that was created when the application was installed had the wrong user/group permissions so it couldn't create the sqlite database. It belonged to root:root and needed to be chown'd to admin:admin.

 

Running like normal now, thanks!
