I use my 3/4 day to test and make an excel table with statistic.
First series test are here:
The new tests:
1.) Nginx without cache can handle in 30sec: 100 users without problem (861ms) or slowly 200 (4017ms).
Without problem monthly "8 640 000" users with that PC in good ping.
2.) OLS without cache can handle in 30 sec: 500 users without problem (775ms) or slowly 700 (3246ms).
Without problem monthly "43 200 000" users with that PC in good ping.
3.) Apache died after Blazemeter test, no help server restart.
Blazemeter.com - very hard real testing! Not only pinging the site.
Without cache - NO ONE ENGINE handled good, terrible statistics...
Only 50 virtual users:
Nginx handle in 2 minutes: 6570ms (can´t use it)
OLS handle in 2 minutes: 2050ms (acceptable, but not much good 2 sec wait only for server)
Apache handle in 2 minutes: Died
With cache CloudFlare and WP Rocket:
Nginx: 0,61679 (good) https://prnt.sc/u50th2
OLS: 0,09579 (very good) https://prnt.sc/u50stf
For both (Nginx and OLS), 50 users in 2 min are: 1 080 000 users in month, what opening only 1 page... That is good, but when no use caches, unusable for bigger site...
