How to implement a real-time chat server in PHP using Server-Sent Events (update: added C benchmark)

Lessons learned:
  • A web server written in PHP can give more than 10000 req/s on small hardware
  • A web server written in PHP is not slower than being written in Java (without threads)
  • A web server written in PHP is 30 percent slower than being written in C (without threads)
  • Realtime applications can be developed in PHP without problems
