实时和PHP？

Question

I'm beginner in realtime applications (e.g : Chat, MMORPG), but I'am good in php and ajax. I have programmed a chat using php and ajax(Interval 1000ms).. After, my site has become very heavy with reason of the large pressure on the server!!

I want information about reducing the pressure on the server.

thanks in advance

Answer 1

Look for long-polling ajax

It requests only once a minute (requests aren't 60/minute but 1/minute)
