I have been experiencing slow downs at my forums as well. I contacted our web hosting provider to try and figure out what was up.

He was get very fast load times. Which I suspected are because he is a guest and is not being logged in automatically.

So I logged out, closed my browser, reopened it and whet back to the main forums page. It loaded far faster than it was before.

I then logged back in and selected to have me logged back in automatically. Now when I close the browser, open it and come back to the forums it loads very fast.

Is if possible that something was cleared by my logging out and back in?
