This has been my experience as well, not to mention how much the client slowed down my machine. It's been really slow going but the client is getting better. I never tried doing the encryption on my side, though, they also do diffs on each file you upload so I imagine that has something to do with the lag. I still use spideroak, they're the only company I'm aware of that encrypts locally and also has done a lot to progress personal security for all of us. So I've gotten used to the slow speeds and buggy software, it keeps getting better so that's a big plus :)
