  • How to optimize memory usage for multiple wordpress in single server

Hi,

Question 1. - How can I check memory usage in wordops?

Question 2. - I want to install 10 wp sites on a single server but after installing my 2 main websites which have over 20K traffic daily, memory usage showing 50%. The server has 4 Gb Ram and 80 GB storage.

So how to optimize the server for fast loading and fewer server resources. Is there any way to install a single WordPress and within that one WordPress installation, I can host all my websites? {Didn't want WordPress Multisite Network Install).

Anyone who can understand my point and if have some tips for me let you please mention here.

Linux tries to use as much RAM as possible, it doesn't matter if your WP sites get 20 or 20k visitor a day. In other words, this is not a metric to worry about.

You should, however, add swap space to your server, at least 2GB. Then keep an eye on it: if the swap usage gets continuously close to 100%, you need a RAM upgrade.

IMHO, DigitalOcean droplets are weak in terms of CPU power. Anyway, a magic number to have in mind is twice the number of CPUs as the top limit to server load (i.e.: 2 vCPUs = 4.0 of server load).

And the most important tip: optimize your WPs, avoid unneeded plugins, and make good use of caches (Cloudflare in front of your domains might be very useful too).
