Server optimization

Sang Le Thanh

Perfomance is the speed at which a computer operates in a time. At our company, it is complete a PHP request

Also, scale have same meaning. And i define it as:

Perfomance: Tweak the system to handle most request without upgrade hardware.

Scale: Update hardware to handle more request.

Make a PHP request complete fastest, that's mean we can handle more request in same time.

We can do it very simple, just install google mod_pagespeed (support apache and nginx)

performane increase 2~3x

PHP is interpreted => When we have a request => PHP is combile a code => run it => return.

Solution: Make PHP is compiled

First time have request => PHP combiled source and store to cache, every request later PHP will using binary code from cache.

Reduce PHP combile time 30~60%

Nginx handle static file faster than Apache.

PHP running via FPM

MySQL: Using MariaDB or Pecona

Ex: An Inner join query without condition make Pantheon server die

I'll have a topic about this in next time.
