It's been working very well for me, I completely replaced Dropbox, and on the VPS/phones [0] as well. The only slow bit I know of is when it's initially syncing too many files (e.g. tens of thousands). Even if they are tiny, it takes a while. I suspect it has something to do with the index serialization, but also there is a maxConcurrentWrites setting which is 2 by default -- perhaps on an SSD this is an unreasonably low default? Not sure. Is it possible that you didn't have inotify enabled (fsWatcherEnabled)? There is also fsWatcherDelayS [0] setting (10 by default), which groups changes to avoid excessive sync operations, so it might be percieved as latency.
