I've noticed that when replying to any thread on my forum, as an user, after pressing reply, it takes roughly around 2-3 seconds to be posted. On Xenforo (here), it's instant. My question is, what am i doing wrong? I'm on a powerful dedicated server and the only thing I didn't do so far is to implement a caching service on my forum. Also, the jquery files are set-up from Google..not locally. Can those 2 things be the reason for this?
