Is Plesk consuming too much RAM?

Jackwebs · Oct 8, 2019

I switch my websites from cPanel to Plesk Onyx but when I checked free - m, I saw my server is using 90% of RAM while with cPanel my server just used around 70% to 80% of RAM. Is Plesk consuming too much RAM?

Hello, greetings.

Not necessary in comparison; In fact Plesk Onyx is lightweight!
Look at number of Plesk Extensions you are using .... also have you optimized the server?

Setup that you have done at cPanel and Plesk Onyx could be Identical but not same!

In free -m , check the column available to know how much memory is available for use.

The “free -m” command displays the total amount of memory.
This includes used physical memory, swap memory in the system and the buffers used by the kernel.

Free Memory = ( Total - Used + Buffer + Cache )

Linux by default tries to use RAM in order to speed up disk operations by making use of available memory for creating buffers and cache. If an applications request memory, then Linux Operating System will free up the buffers and cache to yield memory for the new application requests.

So always consider the sections 'Used + Buffer + Cache ' while calculating the free RAM of a Linux System from a free -m report.
