Hi,

we run:

Apache 2.4.18 on ubuntu
Mysql
typo3

on:
Vsphere 6.5 virtualized ubuntu 16.04. LTS
24 Core, 16 GB RAM

we have Performance issues, i just need to click around the site and load goes up, apache process are easy 95% cpu. The site feels and is laggy when theres more than one person on it.

Even when Nobody is on it cpu load of apache precesses is around 20-30%

Its either mysql or the apache procs going up in cpu load.

I have tried several things like tweak cache settings and hostlookups but i cant get my hand on it.

What else can/should i do to get to the bottom of this? Ive searched around quite a bit but nothing i found or changed so far made it better.
Im not an expert on this...

This is server-status:
