Please upgrade to 2.2 here.
The 2.0 and 2.1 branches are no longer being updated.
Unpredictable response times
We've had some reports (none of my staff/moderators have noticed the problem) but numerous people have mentioned the loading speed of our forums. It seems erratic, not browser based and a number of other websites on our VPS are running very snappily.
Are there any known issues I should be aware of?
