kqueue

kqueue is an efficient event notification system available on BSD-based operating systems, including macOS and FreeBSD. It is designed to handle large numbers of concurrent connections with minimal CPU overhead, making it well-suited for server-side game development. Similar to epoll on Linux, kqueue operates in an event-driven manner, allowing game servers to efficiently manage network events, timers, and file system changes. By reducing unnecessary polling and system calls, kqueue helps improve the scalability and responsiveness of multiplayer game servers, ensuring low-latency interactions and optimized resource usage.
