A poorly coded plugin, a slow SQL query hidden among hundreds of lines of PHP code or a resource-intensive callback function inside your child theme are some of the most common reasons your Wordpress site is slow to load. Like many bloggers, you may be tempted to install a caching plugin or subscribe to a CDN service. But at the end of the day, you still have that problem and you're trying to hide it rather than to solve it.

Fortunately, our Code Profiler plugin is a game-changer for all WordPress users. It brings the power of code profiling applications to the WordPress admin dashboard and makes performance debugging super easy, even on shared web hosting plans: install, activate it and you can start profiling your website like a pro right away.
