Async functions and performance
I want to code online card game with chat, but these issues ruined my ideas. The first issue is that the same loop on node.js (with socket.io) server takes up to 2.5 seconds to execute and on ratchetphp server it takes up to 32 seconds.

```
for ($i = 0; $i <= 1000000000; $i++) {
    if ($i === 1000000000) {
         //....
    }
 }
```

 I knew node is faster than php but such a biiig difference?! I didn't expect.

And another main issue is that functions in my app is blocking and while this loop is running if I or other client sends a chat message to server, chat message function waits for loop to exit.
How can I improve performance, may I use hhvm with ratchetphp? and is there any way to make functions non-blocking?? I want it to handle multiple requests at the same time
Edit: seems like it's very complicated.... gonna try socket.io... closed
