Optimal System Memory

Our server hosts 20-30 websites, mostly small businesses, but a few large churches and schools with high traffic on a 6-core, 8GB container in a EPYC 7402P Proxmox box performance hasn’t been a concern, so I am tempted to stay the course when I configure the next Hestia CT.

But, I am curious what do other see? What if any benefit should I expect to see from bumping the memory to 12, 16 or even 24GB?

It really depends on what kind of traffic have a a few websites that are more CPU intensive memory intensive then it doesn’t make sense but if memory is an “issue” then increasing the memory size is no issue
