CPU resource usage graph explained
If you are a SiteGround customer and you have been contacted regarding your account’s CPU resource usage, you would have received a graph showing how much CPU resources your account consumes. The CPU statistics are visible in your Client Area > Services > Manage > Statistics > CPU Seconds.
The CPU statistics for each account’s server resource usage are generated on a quite complex principle. The graph provides information about the usage on the account and it could be checked per hour, day, week, or month. If you have more than one website under your account you could check the results per website from the menu on the right or select all.
The graph is split in two – the left column shows the CPU time for your user. This is the average time a script started by your account takes to execute on the server. The time is in CPU seconds. The numbers on the left side of the graph show the number of CPU seconds.
The bottom part of the graph represents the time of the number of executions per hour (if this is the selected option) your account makes.
A simple example of execution is when a visitor opens your website and your index file is loaded. This counts as one execution. The more visitors your website has, the more executions it will generate.
