High CPU usage is a very common issue when it comes to shared hosting. The shared server hosts a number of websites and many of them are running PHP processes and MySql queries.
What may create a High CPU usage problem
All the below-given things are the potential causes of high CPU usage.
- A lot of WordPress installed regardless of whether they are getting low traffic
- Resource-consuming plugins installed
- Real-time stats collector plugins
- The high number of online visitors
- Longer duration Simultaneous download connections
- Running frequent and long-run cron jobs
How to reduce High CPU usage:
This might be a difficult task, especially if you are working with third-party web applications like forums, blog systems, or content management systems as you might not be having detailed information about the functioning of these systems.
However, there are other things that can be implemented for reducing CPU usage:
- Upgrade all the third-party web applications to the latest version available (including WordPress, Drupal, Joomla, and any other content management system or blog systems, galleries, forums, or any other scripts that are installed on your account)
- Check if there are any add-ons or plugins used on your web applications, and make sure that they are upgraded to the latest versions as well
- Perform a general check and make sure that any of the unused plugins, add-ons, or web applications are removed
- Any of the web applications that allow the ‘caching’ feature, should have this feature enabled or activated
- In case you have developed your own scripts, try reducing the number of MySQL, MSSQL, and Postgre SQL queries for optimizing your scripts so that they need less processing time
- Avoid spam messages or comments on your site.
