In our previous example, we would have one-minute load times of.

A completely idle processor would have a load value of 0.

Instead of measuring the percentage of time that the CPU is working, CPU load measures how many programs are using or waiting for a processor core at one time. You could downgrade your processor to a lower tier, save money, and see no reduction in the quality of your server’s performance. Most servers are sold by overall computing power, and if your server is only sitting at 30% CPU usage, you’re paying for too much processor power. Most companies seek to keep the CPU usage of their servers as close to 100% as possible. Instead, if the program only required six seconds processing time on one core, the usage would be 10%. For instance, if you had a program that required uninterrupted processing power for 54 out of the last 60 seconds, your CPU usage on one core would be 90%. CPU usage is a measurement, in a percentage, of how much time the CPU spends actively computing something. Even though they might sound similar, they’re quite different. The first thing to understand is that CPU load is not the same thing as CPU usage.
