Nginx Concurrency Estimation and Load Testing
To estimate the maximum concurrant connections Nginx can handle, use the following formula:
(Total RAM in GB × 1024 − System Overhead) / Average Request Size
Total RAM in GB: Physical memory available on the server.
System Overhead: Memory reserved for OS processes, background services, and buffer space (typically 2–4 GB).
Average Request Si ...
