4 Reasons Why Your WordPress Backend is Slow

Ever wonder why your WordPress backend is so damn slow?

Using plugins we can cache the WordPress front-end, but sometimes the WordPress backend runs very slowly. So let’s explore 4 reasons why your WordPress backend is slow and how to speed it up;

1. You may have far too many plugins on your website.

Each plugin adds to the memory usage of a website, the more memory usage of a website, the more data that needs to load and ran in order to load that website. This all adds to the overall speed of a website. So just install the plugins you actually need.

2. One or more of your plugins may have a memory leak issue.

This means one or more of your plugins might not be written as well as you’d expect, giving you a bunch of unanticipated problems. What you’ll need to do is slowly deactivate your plugins one-by-one to identify the slow plugin, which once identified you should seek an alternative plugin.

You can use a plugin called P3 Profiler, or another plugin profiler to track down the least efficient plugins presently running on your WordPress.

3. Your WordPress, theme(s), and/or plugins might be out of date.

Keep everything up to date to ensure you are running the most recent version of the items. If you have a custom plugin or theme, it might be best to contact the developers and see if they can identify any issues.

4. You may have ‘Object Caching’ enabled in W3 Total Cache.

There is a butt load of caching plugins out there. We recommend WP Fastest Cache or W3 Total Cache and see if that makes a difference in your site.


In a lot of cases, your host’s servers could be to blame, the best way to identify this is to see any other websites that are running on that same server and see if those sites load slowly too. However more often than not the issue is with an improperly configured caching engine, or too many bulky inefficient plugins.
