I also did note that you had 13 active httpd processes at about 3% each.
If you have a quite a few people active connecting to the Web UI you may need to up the processing power to handle these.

Hi,
Strange because we're only three to access Nagiosxi.

It could be that the ps information you had was just for a short time window and httpd isn't a big user.
Looking again at the image you posted it looks like you are averaging about 60% CPU utilization with 2 CPU's allocated.
With the quantity of hosts/services you have the recommendation is 2-4+ CPU cores so you may need to add more as this increases

Hi,
You can close the ticket : I removed the checks on ESX servers using check_esx3.pl.
That decreased the performance problems by half.
Now I only check ESX availability (services are monitored by Veaam monitor).
Thanks,
Frederic
