RHEL-8 Kernel Settings

Hello

I’m looking for assistance in determining kernel setting for a VM RHEL-8 linux server running postgresql-13.


I have 3 server groupings

1)   2 vcpu’s  8gb memory
2)   4 cpu’s 16gb memory
3)   8 cpu’s 32gb memory

I’ve read various articles and the PostgreSQL documentation .   Does anyone have practical experiences doing this kind
ofset up 

Do kernel setting requirements change based on the number of cpu’s and amount of memory?    I’ve not read any mention
ofthis. 


Regards

John W
