Nginx performance optimizations

The configs below are for Linux.

These are the most competent tunings I've found.

default.conf

server {
    listen 80 default_server deferred;
    listen [::]:80 default_server deferred;
    listen 443 default_server ssl http2 deferred;
    listen [::]:443 default_server ssl http2 deferred;
    server_name _;
    
    # ... the rest of your config
}

nginx.conf

worker_processes auto;

events {
    # http://nginx.org/en/docs/events.html
    use                 epoll;
    worker_connections  2048;
    multi_accept        on;
}

http {
    # ... the rest of your config
    
    sendfile            on;
    sendfile_max_chunk  512k;
    
    tcp_nopush   on;
    tcp_nodelay  on;
    
    # use this only when your nginx server serves static files
    open_file_cache           max=1000 inactive=20s;
    open_file_cache_valid     30s;
    open_file_cache_min_uses  2;
    open_file_cache_errors    off;
        
    # ... the rest of your config
}
