eAccelerator is a free open-source PHP optimizer & accelerator. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. Enhances execution of scripts. It typically reduces server load and increases the speed of your PHP code by 10 times. Stores compiled PHP scripts in shared memory and executes code directly from it. It creates locks for a short time, so one script can be executed at the same time by several engines. Files that can’t fit in shared memory are cached on disk.
Installing eAccelerator on your linux dedicated/VPS can be achieved by just one command.
# /scripts/phpextensionmgr install eAccelerator
Check with the command below if eAccelerator has been installed properly.
# php -v
The above script/command will install & add the extension in server’s php.ini file. Our cPanel hosting plans have eAccelerator v0.9.6.1 installed.
