i am having issues with CPU high utilization, more than 92% .

Is there anyway to track which plugin or process or user is causing this issue?

Will usage of any cache plugin will help this or not ?

  • this plugin should do the trick. (Helping you to find which plugin uses too much resources (possible reason for too high cpu/mem use)

Simplest way to see what is causing it is to disable all plugins and add them back one at a time. If that doesn't reveal it, switch to a default theme. After that I'd say it is something server side.

To answer your question though - caching should help but it depends on what is causing the high usage.
