I have installed Site Statistics for over a month and it was good for a while. Now that I have more visitors, my site keeps going blank and my other sub-folder website keeps getting 'max_question' resource exceed etc... So I cannot have more than 25 simultaneuos visitors.

I decided to uninstall Site Statistics and now my site doesn't use as much resources.

If you have similar experience, disabling Site Statistics on your page will save loading time and save resources.

What you report is quite well known, which is why very busy sites prefer to use server logs rather than web based statistics trackers.
