CentOS handled that situation reliably; while there were some difficulties changing some settings inside the application, once I managed to tweak the settings, it worked very well, allowing around 10,000 users to connect and chat simultaneously.

CentOS should provide updates more regularly. Kernel parameters, sysctl config details, tuned profiles, process prioritization, optimized disk, and input scheduler choice are all points for performance optimization.

CentOS, being Linux-based, is the best in security, but it needs more on the security side for CentOS RADIUS server.
