cpu

I'm learning to manage a VPS I know about ram, cpu cores and ssd but I don't know which is the most important for a VPS to run perfectly? Please explain me.

Hi, I'm using a linux VPS with 8 CPUs, RAM 2GB..for running my php sites but sometime my sites load slowly for 1 or 2 hours. It was affected by CPUs or RAM? also I want to check speed of CPUs, it's possible?
