Hey guys!

lately at about 2 am my servers take time to open my sites, i was suffering before of msql overload and cpu overload in which I had to restart webserver for my sites to load but that was before.

Now It just takes longer for the sites to open at that time, i check cpu load and is less that 1. I go to sleep and when I come back sites are fast the rest of the day.

any suggestions?
