I have a laptop with windows 8 and a 5400 rpm hdd, using the latest stable release(0.14.25).
The problem is, that syncthing eats up disk io during synching, not always but a lot of times.
Task manager usually show 90-100% disk usage from syncthing. I set the copiers and hashers to 1, pullers on 0(tried with 1, but as far as I remember didn’t helped), output rate set to 1000KiB/s on the sending machine.
Any suggestions what should I do to make it more usable on this machine?
Is Syncthing still performing an initial scan? If this is the case, it will consume high I/O until it finishes, as it has to compute and save hashes for all of the data. If not - what is Syncthing doing during these high periods of I/O? Try running Sysinternals’ Process Monitor to see what files it’s accessing.
It’s not just the initial phase, I’m experiencing problems during sync too, I think the slow hdd is the main cause. Now I start syncthing with -background priority, which is available from Vista and set the I/O, memory and cpu priority to very low.
Better now, but need some extra testing.
