strange lag on forums

[Big G]

according to my activity monitor all 4 cores are ticking along at <5% usage and my disk activity is low also, yet the forums seem to be a bit sluggish.

When I type the words don't always appear as fast as I press the keys. Mainly in PM's.

Anyone else getting anything like that? I'm running a lot of stuff, but this is normal for me and it's never done this before.
