It’s the most vital part of this whole process that you can’t afford to avoid. If you conduct the following steps on your live site, it may harm the site. As it involves deactivating the plugins, there is a chance of breaking certain features that depend on the plugins.

So, before implementing any of the following steps, set up a staging environment of your live website. After that, you can run the test on your staging site without creating any issues with your live site.

3. Remove or Deactivate All of Them

Now, go to the plugin menu from your WordPress dashboard and bulk-deactivate all of them. Then run a speed test; you can do this on a new device or browser to avoid cached page skewing test results.

Remember, there should be one plugin active at any given time to discover which one is creating a slow loading speed.

5. Delete the Slow Plugins

As you conducted this test on your staging environment, so you don’t have to reactivate the plugins there. Instead of doing that, once figuring out the slow plugins, go to your live site and delete them permanently. So, confirm the deletion and check for the improved speed in your live website.

6. Find the Faster Alternatives

In some cases, you may require replacements for the plugin you have deleted. So, find out the high-quality and high-performance plugins, then install and configure them.
