[FIXED] How to improve PHP performance?

Issue

I've created PHP application for Facebook. It uses MySQL, Memcached and works on Lighttpd on Centos 2,6 Ghz and 2 GB RAM.

it's basically one PHP file that after first run is cached and every next time it's served in 0,8 ms directly from Memcached.

What more can I do to shorten this time?

Solution

Once you get to 0.8 ms, I'm not sure you can go any lower.

However, you can set up multiple servers to handle many concurrent requests (with a common memcached). You will then be able to scale very high by simply adding a new server when you reach limits.
