Troubleshooter on high CPU Usage for WordPress websites

Multiple CPU utilisation issues are currently pervasive in WordPress websites. When you utilise shared resources or a hosting package with less resources, they even become more common. But even with an excellent hosting plan, CPU use issues might occur. When that occurs, your website becomes slower even when there are no resources available to provide information to it.

Additionally, issues with CPU utilisation can quickly hurt your website’s rating and result in a bad customer experience.

This post will teach you how to fix WordPress websites that are using a lot of CPU power. All of the techniques we use are straightforward and simple to implement. You could always hire a developer to complete the task for you, though. So let’s get going!

Steps for Troubleshooting on High CPU Usage

1) First of all, confirm that you are using the most recent versions of the WordPress core, themes, and plugins.

2) Next, examine the scripts to see if there have been any illegal changes or unidentified scripts inserted into the webfiles.

3) Add an extra layer of complexity to all of your hosting accounts’ passwords (consists of symbols, alphanumeric characters, lower and upper case letters). such as your CMS login password, the hosting Control Panel login, and FTP login.

4) Run a local computer scan using a trusted antivirus programme, then install Microsoft Security Essential on any Windows-based systems.

5) Investigate the issue by turning off the WordPress plugins that frequently result in excessive CPU utilisation, then get in touch with us.

6) For websites that use html pages, think about adding this WP Plugin -> “WP Super Cache.” a WordPress caching engine that is incredibly quick and creates static HTML files.

7) As an alternative, consider using the helpful plugin “DB Cache Reloaded.”
Within a specified lifespan, this plugin caches each database query. It consumes less disc space for caching and is significantly quicker than other html caching plugins.

Here are some tips for Best Result:

1) Carefully examine the index.php scripts (look for any strange or injection scripts) in this file.
2) To identify which plugin is causing the overload, check and disable all of your WP plugins before enabling each one one at a time.
3. Use more complex passwords for all of your hosting logins, such as FTP, WP login, and Control panel login.
4) Update all of your hosting webfiles, third-party applications, plugins, and themes.
5) Use a reputable antivirus programme to scan the local machine you are using to connect to the hosting. Install Microsoft Security Essentials if you are using the Windows operating system.
