Hi guys, I am having some issues with 2x new servers I am managing. I am currently hosting 45+ CSGO servers for local divisions in my country and all servers have been performing well.
They are all running CentOS and have been very stable for the last 3 years.
I recently got 2x new servers from our sponsors (used servers) and I set the servers up exactly like the older ones with identical server configs, plugins and stuff like that but these new servers are just not performing well. The SV is anywhere from 5-10 and the VAR is spiking very high as well.
The only difference from the older servers is that these servers are running Ubuntu.
The servers are all located in professional server facilities and have 10GB internet connections.

Do you guys have any ideas what might be causing these issues for me? I have been experimenting with all sorts of combinations of commands with no results.

New server specs are:
1st server:
2x Intel(R) Xeon(R) CPU E5-2630 v2 (24 threads total)
64GB RAM

2nd server:
2x Intel(R) Xeon(R) CPU E5-2650 v2 (32 threads total)
64 GB RAM

Server CFG:

The CPU when all servers are running and full og users is about 50-60% and RAM is something similar.
