Hello. I am running 4 servers with these specs:

HTML Code:
OS	Ubuntu-20.04 (4 bit)	 
RAM	18000 mb RAM (18gb)	 
CPU	5 x 3 GHz vCPUs	 
SSD	80 GB	 
Bandwidth	200 Mbps

Servers actually have no lags if there are less than 20 players on each. When any server hits 20+ players, CPU % of that server jumps randomly from 20% to 100% for like 3 seconds and then it backs to normal so players are complaining that once per minute they have huge latency which jumps randomly but not always. Each server has 64-75 plugins running and all modules are enabled. I've changed sv_unlag 1 to 0 because 15-20% players usually have 100+ ping so I thought they cause lags others, so I've turned the compensation off but it didn't solved a problem.

Maybe important to mention rates and commands?
HTML Code:
sys_ticrate "1200"
sv_minrate "25000"
sv_maxrate "100000"
sv_minupdaterate "0"
sv_maxupdaterate "102"
sv_airaccelerate "100"

sv_maxunlag "0.5"
sv_unlagsamples "1"
sv_unlagpush "0.0"

Any ideas of what could be wrong? Host providers told me to take a look on servers itself because these specs should be enough to run this amount of servers when they're full.

Virtual cpu? Shared hosting?

Lowering the tic should help.
