I am using Debian Apache2 & ISP since some years now and it's always very comfortable experience till date. Recently i worked on a government website that we hosted on my personal server for time being. On day of promotion, website received 65000+ hits in just 2-3 hours. This crashed Apache completely and overall performance of server was completely compromised. All other websites also went down and response time was almost 4-5 minutes per page.. so many requests aborted.. lot of mess.. this server is 4c8t, 16GB RAM, Debian, Apache2, mySQL, ISP3.1.13 .. it's php7.3 fpm configured with higher limits. Experts advising me to install nGinx instead of Apache2 to get better experience. All my websites are wordpress & drupal. I always have multiple users & authorities on all CMS. I also have some membership driven websites in wordpress. So caching is always not solution for me. Many pages have custom code, blocks those need to be dynamically presented as per logged in user. Apache does this all well & I never faced any issue. Now the question is, will that be same experience on nginx? will wordpress & drupal behave same. They say nginx is 2.5times faster than apache. But while this speed, its equally imp for me to present dynamic content per user. will that happen? I m already upgrading to higher config server with 32GB RAM & NVEMs.. so i want to take call whether to install apache or nginx on this new server.. plz advice..
