# Overview
> Pick a PHP version, install Perl and PEAR modules, run AccelerateWP for WordPress performance, and trace slow PHP requests with X-Ray.
The Software section is where you control what runs your code: which PHP version, which extensions, which WordPress optimizations. Two of the most useful tools (Select PHP Version and AccelerateWP) come from CloudLinux, which is why they're more capable than what stock cPanel ships with.
## PHP
Pick a PHP version, toggle extensions, and tune `php.ini` settings without SSH.
Profile slow PHP requests. Find out which function calls are eating your TTFB.
## WordPress and site speed
CloudLinux's WP Rocket-style speed plugin. Page caching, JS/CSS minification, lazy loading, database cleanup.
Toggle Apache mod\_deflate compression. Use with care.
## Modules and packages
Install PHP libraries from the PEAR repository.
Install Perl modules from CPAN.
## Common starting points
Start AccelerateWP with the suggested defaults.
Switch the active PHP version in two clicks.
Trace a request with X-Ray and see which function is responsible.
Toggle the extension on the Extensions tab.
## Need a hand?
Best for anything that needs an account check or a config change on our end.
Faster for quick questions during business hours.
