What is Ngnix Max Open Files Limit?
The Nginx maximum open files limit refers to the maximum number of files, including sockets, that the Nginx process can have open simultaneously. This limit is determined by the system-wide file descriptor limit set by the operating system. File descriptors are used to represent open files, sockets, or other I/O resources.
For Nginx, a high maximum open file limit is essential, especially in scenarios with high traffic or many concurrent connections. This limit impacts the web server’s ability to efficiently handle multiple requests concurrently. If the limit is too low, it may lead to connection issues, dropped requests, or sub-optimal performance.
