Hi there

I have a problem with high cpu from k2.
I have three website where is copy paste only change is the domain. Also they use all the same component - plugins.
Joomla is Joomla! 3.10.12CPUAMD EPYC 7282 16-Core Processor (8 core(s))VersionPlesk Obsidian v18.0.61_build1800240703.08 os_Ubuntu 20.04Operating SystemUbuntu 20.04.6 LTS
Memory Usage 30gb

This problem is only with one of three website
coupaki.gr

I find in forum 3 months ago that if i change the database from mysam to innod work fine. I make it and all worked fine until three day ago.
Only one website (coupaki.gr ) need 6~12 cpu and because we are in vps host 500LVME GB all site is slow or 500

Is anyhting else to check for this problem?
Thank you
