Yeah already did. Have come a long way since it was posted.
Right now, using latest Ngnix, PHP 7.2, MariaDB, HTTP2, Redis, Brotli for WP sites.
My problem was I was running a quite big server with just a few sites, applications, and storage use after I scaled up for certain projects.
RAM 144GB, CPU 72 Cores, 4TB NVME
c5.18xlarge - AWS
Earlier used to have instance or server sizes upto 8GB, which worked really well when optimized and configured with right values.
So though Ngnix out of the box with EE is good for small instances; MySQL, php, Ngnix configurations doesn’t scale at all.
You have to manually test it in a hardcore way over time and alter the values to make your applications (for me WP and some other running apps, data research) here to make sure utilize all the spare resources; so nothing remains underutilized.
So at present, optimization and concurrency resulted in my server usage of more computes, such that it barely uses 10GB out of 144GB RAM.
Though with more depth trails and figuring out the values, I think I can achieve more performance from the server.
About Trellis; way back I used it on a 32GB server; fired up the same demo sites and some heavy virtual load and it seemed Trellis configured better than EE and performed far better.
So, in the end, its all about each individual use case scenario, the server they are using and how well they have squeezed the performance out of their server for their websites.
Right now what we EE enthusiasts want is to get upto date stuff with EE.
I asked some acquaintances to do a fork EE and work on updated stuff; however, they are busy with their own projects.
So its bit troublesome to find the right values for my server. I don’t have the time, and it’s better to learn things than to spend on something unless it’s about security.
