Hello,

I hope you can help me. I have a site that I'm moving to a new datacenter. The server is pretty much vanilla, no control panel, and also no optimizations. When I hit a page, the site takes an extremely long time to load, despite it being relatively light weight. I ran top to see what was happening, and the cpu jumps to 75%, and drops back down to about 20% while the rest of the page is loading.

Someone suggested that I ran lsof -p on the offending processes, but I'm not sure what I'm looking at. I ran through my httpd.conf file and commented out a bunch of loaded modules that didn't seem necessary, but that didn't help either. Anyone have any ideas?

Output of the lsof http://pastebin.com/mfa113f

disparity between `top`'s given CPU % and process CPU usage total

I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop. As an example: I recently ran a git filter-branch --index-filter on a fairly large repo, with the index-filter command… >>> More
