Congratulations for SyncThing. It has gone a long, really long way since I last checked it.
It is a pity that SyncThing does not support natively event driven file system change notifications instead of just (the much more resource expensive) pulling requests… at least under the windows platforms.
I expect there might be some good reasons for this. I also expect that this missing feature request may soon be added in the top priority list of future releases.
I tried SyncTrayzor, but it seems it is not possible to run this program as a system service under a restricted account and have the front end communicate with it under a regular windows user account.
I also hope the SyncTrayzor feature of setting the SyncThing process priority will soon be added to the main SyncThing program.
Overall, adding both of the above features will make possible to run SyncThing on older PC hardware as dedicated boxes.
