Doesn't it get slow? I'm running Firefox with a profile on a mounted sshfs directory, and it freezes for a few seconds quite regularly, despite having a decent connection.

Nobody's complained, and I am one of the people responsible for fixing such complaints.

ISTR Firefox does an awful lot of writes in order to maintain state; https://www.servethehome.com/firefox-is-eating-your-ssd-here... is from more than a year ago, but I wouldn't be too surprised if something similar were happening to you.
