High Apache CPU usage on 2 GB Droplet

About to move a site to a 2 GB Droplet, but I keep seeing high CPU usage hyst by clicking on the home or on any other page.

I have Varnish in front of Apache, with APC and PageSpeed configured. Even with that configuration, I still see an Apache process gunning at more than 100% (yes, that’s true).

I’ve messed with the plugins and tweaked mpm-prefork settings, but have not seen any change.

If it will help, here are my prefork settings:

StartServers                     5
MinSpareServers              5
MaxSpareServers           10
MaxClients                   150
MaxRequestsPerChild 3000

@natwar86: First you need to find out what process is using up a lot of CPU. You can run “htop” (run <code>sudo apt-get install htop</code> to install it if you do not have it installed it) and then press “P” to sort the processes by CPU usage.

Has anyone been able to figure out what’s happening? I got same issue… <br> <br>

Look at the graphs he’s using to back up his claim, then picture what “10 millions hits a days” means. <br> <br>The process of setting up the system is not the misleading part, it’s the “10 millions hit a days.”
