How does more RAM and CPU increase website performance?


Hi all,

when typing this question in Google, the responses are quite diluted, with many results focusing on the RAM of a personal computer rather than that of a hosting provider.

I'm sure many of you here are good at SysOps and can answer this question better.

My website runs WordPress. I get around 30,000 visitors to my website monthly. I am curious on the technical parts of how adding more RAM/CPU is going to increase the performance of my website. At the moment, even when I have 50+ visitors on at the same time, my CPU usage doesn't go very high, and neither does the disk.

So, if I were to upgrade - is it going to be something that I can literally notice the moment I do it?

adding more resources won't help unless you're resource constrained. CPU Cores and thread are also resources.

So no. You'd probably see more improvement from a CDN.
