You can install eAccelerator, a free open-source PHP accelerator, optimizer, and dynamic content cache to improve the performance of
cloud hosting/
Dedicated Server. Here are the key benefits of this open source application:
• It increases the performance of PHP scripts by caching them
• It optimizes the script to gear up the execution
• It reduces the server loads and speed up the performance by 1-10 times
Please make sure that it doesn’t work correctly with SuEXEC, it implies that if you wish to have eAccelerator installed on your server, the Apache
web server is required to be recompiled without SuEXEC support. After that the files uploaded by the visitors cannot be modified through
cPanel or FTP. On the top of it, the removal of SuEXEC and the usage of eAccelerator will increase the security concerns.
