Lol, yeah that was your mistake. FUSE is a phenomenal idea but anyone who has used it knows how slow it can be.
Also, it's a great illustration of the benefits of layered, modular design that Linux sports: it allows to mix and match parts to build what you need.
Have you tried the sync feature?
Edit: FML why is this being downvoted? At least have the decency of explaining, I'm happy to adjust my conduct but I can't do so if I don't know what I did wrong.
