Hello friends, back in 2015 one of the guys on my FB list optimised my Digital Ocean 512 MB RAM VPS. I was using frotier theme & minimal plugins. I have tested it at around 3000+ concurrent vistors. Today i have 512 MB VPS & i want to test it once again, I don't have his contact unfortunately. May i know which NGINX configuration can handle that much traffic???? Pls. share your personal experience as well.
For ex: NGINX + Mysql + PHP-FPM + Redis
Like this i need your expert advice on what all needs to be installed & optimised. Thanks
