It is considered (rigthly in most cases) that it's a bad manner to implement a daemon using PHP. It's OK for prototyping but no-no for production. That were our thoughts when we've started to implement a new version of browser game. It was planned to describe an interface to communicate with daemon that will be then rewritten in pure C. However, fist libevent PHP daemon performance tests forced us to think if we really need to rewrite it in C. What was the performance? Are there memory leaks? All these will be covered in the speech. You will also learn about problems, features and how a real project results.
