How much RAM is required for 3k daily visitors?

I would advice not to use anything less than 4GB. I am a fan of higher RAM usage in order to increase the speed of your data processing.

If you don't go wrong, your mentioned config should be enough. But to feel comfortable you can raise your config bit like 4GB RAM. But most important is optimization. It should be in a proper way. Good luck

I think for VPS, it's very easy.

You can start with a smallest configuration and watch the report of RAM and CPU usage to see if RAM or CPU reach over 90% e.g.... upgrade your VPS to higher configuration

Most VPS providers has well support to upgrade, just some click and take couple of mins...
