Easyengine optimization 10000 visitors

hello how to do an easyengine optimization which can lift 9000,10000 visitors instantaneously
Note: daily visitors total 300,000

System: 3.75 gb ram 1 CPU / Google Cloud

This doesn’t seem like anything you’d need to do any special config on. On the base ee install I can throw a million daily hits to my server with no noticeable slow-down. Since you’re on Google Cloud though I think you will notice some slow-down but not that much for 300k daily hits. I think for you best to leave everything on automatic based on the vCPU and RAM you’ve got. And if your visitors are from all around the world this would probably be an ideal situation to use CloudFlare CDN (it’s free) to offload a lot of http requests and bandwidth to them.
