eAccelerator is a open-source PHP accelerator & optimizer. It helps increases the performance of PHP scripts by re-using in their compiled state, so that the extra of compiling is approximately completely reduced. It also optimizes scripts to speed up their execution.

eAccelerator naturally decreases server load and increases the speed of PHP code by 1-10 times. It stores compiled PHP scripts in shared memory and executes code directly from it.

How to Install eAccelerator in Cpanel

In cPanel eAccelerator installation is very simple and fast following these two steps:

1. Check PHP runs as DSO Apache module.

For this reason log into cPanel server WHM and go to 'Configure PHP and SuExec'. There confirm that the PHP 5 Handler is set to dso.

2. Next log in as root by ssh and type the following command:
/scripts/phpextensionmgr install EAccelerator

With the above simple and easy steps our PHP performance should be significantly get better with the facilitate of eAccelerator.

eAccelerator will help speed up websites loading speed, it is important to realize how php scripts are executed and run to power websites.

The MMCache extension for the PHP programming language inspired eAccelerator, a PHP accelerator. A bytecode cache is provided by eAccelerator. eAccelerator is free to use and distribute because it is open source. An encoder was also included in older and unmaintained versions.

eAccelerator is a PHP accelerator and optimizer that is available for free. It improves the efficiency of PHP scripts by caching them in their compiled state, almost eliminating the overhead of compiling. It also optimises scripts to make them run faster. eAccelerator decreases server load and speeds up your PHP code by 1-10 times on average.

eAccelerator keeps compiled PHP scripts in shared memory and runs code from there. It only produces locks for a brief period when looking for a built PHP script in the cache, allowing one script to be performed by several engines at the same time. Files that are too large to fit in shared memory are cached solely on disc.
