Nginx Worker Calculator
Work out worker_processes, worker_connections, and the file-descriptor limit that needs to match them, from your core count and the concurrency you actually expect to handle.
Effective max capacity
nginx.conf block
worker_rlimit_nofile must also be raised at the OS level (ulimit -n
or a systemd LimitNOFILE override) — setting it in nginx.conf alone
won't exceed the OS ceiling.
