What is eAccelerator ?

eAccelerator is a free open source PHP accelerator, optimizer, encoder and dynamic content cache for PHP. It increases performance of PHP scripts by caching them in compiled state, so that the overhead of compiling is almost completely eliminated. Also it uses some optimizations to speed up execution of PHP scripts. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.

To install it you need to follow the below mentioned steps:
# wget http://space.dl.sourceforge.net/project/eaccelerator/eaccelerator/eAccelerator%200.9.6.1/eaccelerator-0.9.6.1.zip
OR
wget http://prdownloads.sourceforge.net/eaccelerator/eaccelerator-0.9.6.1.tar.bz2?use_mirror=ufpr

Optimization, PHP

I have found the post by Reinhold Webber, which provide good techniques and methods for PHP performance and optimization. I have tried to add more explanation to the points posted by Reinhold Webber.

1. If a method can be static, declare it static. Speed improvement is by a factor of 4.
2. echo is faster than print and print_r.
3. Use echo’s multiple parameters instead of string concatenation.
4. Set the maxvalue for your for-loops before and not in the loop.
5. Unset your variables to free memory, especially large arrays.
6. Avoid magic like __get, __set, __autoload.
