I looked into it for a week and can’t figure out what the issue is. I have an AWS setup with separate rds and relatively big server. Static files offloaded to CDN and Redis for page caching.
Here’s the problem. There’s a significant slowdown of the setup with every new Virtual Host. I found a couple of DDoS throttles on EE setup and I increased the number of requests. However, it’s still significantly slower. How?
One setup for 1 website loads entire site below 1 second. Add 10 more different sites, the same site loads between 3-5 seconds (based on newrelic).
First you’ll say that it’s a traffic issue. So I thought so I duplicated my setup and connected via hosts file from my computer to make sure that there’s only my traffic coming to the server. And the same speed.
I feel there’s some kind of setup somewhere on EE (or maybe on default nginx?) that makes it slower with growing vitual hosts.
Any suggestions would be much appreciated!
