The http servers drag race finished 15 years ago on a tie, it's really much a matter of taste and familiarity more than performance at this point.
replyThe lazy bastard in me prefers Caddy.
replyI don't understand this. NGINX can run PHP. PHP is not exclusive to Apache.
replyIn general, the Apache php mod has had less drama than php-fpm over the years. Also, casting each domain under specific isolated itk server user(s) account(s) adds a layer of containment, where Nginx processes must run under a single user context.
replyNginx uses way less memory in most use-cases (1/4 to 1/10), but with dynamic content like php it is only slightly better (maybe 15% if lucky). Also, setting up websocket proxy in Nginx is still a bit of a bodge.
Each server type has its own trade offs, and a list of known mitigations the uninitiated must learn. If you have a single domain high-traffic site with static media files, than Nginx is probably going to matter more. =3
