It's not server related.
It's how browsers are processing the forum style by the looks of it. As a mod you can use the stock forum style which should sort it out I think (although can't remember who think it was Marvo who still had some lag even on that which is weird).
Close all browser tabs. I found when I had a shed load open it lagged once one time but haven't been able to replicate it since. Not sure why.
I think you might be able to get rid of WYSIWYG text editor via your forum settings (mark / whitebeam did it by accident) which might help the processing of typing.
