I'm using BTsync between one Macbook Air, one Android phone and one Raspberry Pi, and I've upgraded all the client to 1.3 already. I found several issues, BTsync keep a very high CPU usage on my Raspberry Pi, the lowest situation is around 3x%, and goes to 70%~90% usually, is this normal? On the MBA , only part of the syncing folders being showed in the "Device" windows in my Mac client, some of the folder wouldn't be showed after the first setup, My android client never found the RPi when it is using mobile connection, Good news is that, after upgraded to 1.3, my MBA can find the RPi even the MBA on my office network and RPi stay behind my home router.
