Average resource usage on Centos7 + CWP ?

I am running 2 php websites on 6 core 2.2Ghz and 16Gb ram.
Sites are on identical small php scripts (robocripts csb) , 100mb DB each.
Before i was using tmd shared hosting and these 2 sites has enough power to run.

Now on CWP and on not bad VPS it seems 2 scripts are eating quite a bit of resources.
Apache -> php-fpm 7.2.
About 100 users per day on 2 sites , do you think is it normal:

I have these spikes on each site visit. And on cron run i think (i have 3 and 8 minutes crons for each site).

On idle load:

Can you guys share your servers load ?

Very strange. One day i have with zero users online ~90% cpu load , next day with 3 users browsing right now :
