I am running a website on an Apache server. The server itself is an 8 core server with 35G RAM. I am monitoring the statistics of the apache resource usage and the overall server resource usage.
I noticed the CPU usage of apache actually goes over 100%, even up to 150%! How is this possible?
Looking at my overall CPU utilization across all my CPUs, it is only around 0.3.
Currently, from Google Analytic, there is around 400 users viewing the website simultaneously. I am also browsing the site and refreshing pages just to test, everything seems smooth.
So my question is, is this apache CPU usage stats something I need to be worried about?
Any help would be appreciated.
