Statistics and mysql server load

In my 1.3.5 version I have enabled Statistics module. Can anybody tell how much this module loads a mysql server? In general with my host provider any php carts (I tried some) work slower, sometime much slower than plain HTML pages. So I should to find out what I should turn-off in the CS-Cart to improve speed of the site.

If you’ve got a ****py host then never turn it on, that said if you’ve got a better host you’ld proberly be better of finding another script for your uses.

In my testing store speed is halfed until the statistics mod is turned off.
