uiDivStats Web browsing completely impacted nightly apparently by uiDivStats record trimming?

[crezam]

I have noticed while I browse the web, every night from all my devices there is timeouts after midnight for about 6 or 7 mins. From the logs appears uiDivStats trimming happens during this time.

1. Is this supposed to be such an intensive process that consumption of router resources impacts web routing?
2. Could this be a problem with my current DB? Im thinking of resetting it
3. Wouldnt mind if this happened while I sleep (say 4 am). Is there a setting to change time?
