I've been noticing poor performance too, in addition to some weird bugs. I've had files completely disappear, the response from support is attached below. I still don't have those files back, they were not critical but now I have learned to use dropbox for (slow) syncing between machines, and use an external drive for redundancy.

Support response:

The event you've provided shows and deletion of 12 files as well as an addition of 12 files. When this happens in the exact same event, it is due to a move or to renaming a folder 99% of the time.

To recover your correct previous versions of these files, you may be able to rename the folder back to exactly what is what named prior.
