Having a fast WordPress backend is crucial for a seamless user experience. Let’s face it, no one likes waiting for pages to load, and a slow dashboard can seriously affect your productivity and frustrate your users.

Think about it, you log in to your WordPress dashboard to create new content, update plugins or themes, or manage your site. If the dashboard is slow, you may have to wait several seconds for each action to load, which can add up to a lot of wasted time. This can be especially frustrating if you have a lot of content to manage or a large website.

Before we dive into optimizing your WordPress backend, it’s important to understand your website’s performance. Analyzing your site can help you identify the root cause of your slow WordPress backend and make informed decisions about which optimization techniques to apply.

Update the WordPress Version to Optimize the Admin Bar

One of the most common reasons for a slow WordPress backend is outdated software. It’s essential to ensure that WordPress, as well as plugins and themes, are updated from the older version to the latest versions.

WordPress updates include bug fixes, security enhancements, and performance improvements. By updating to the latest version, you can take advantage of these improvements and ensure that your site is running at its best.

To update WordPress, simply navigate to the dashboard and check for any available updates. WordPress will notify you if an update is available, and you can update with just a few clicks. It’s also a good idea to enable automatic updates for WordPress, plugins, and themes, so you don’t have to worry about manually updating them.

Outdated plugins and themes can cause compatibility issues and security vulnerabilities, which can slow down your site and put it at risk. So, it’s always a good idea to update all plugins and themes as well.

Check Your PHP Version to Improve Load Times


Another common reason for a slow WordPress backend is an outdated PHP version. PHP is the programming language that WordPress runs on, and newer versions of PHP offer significant performance improvements.

To check your PHP, you can navigate to the “Site Health” section in your WordPress dashboard or WordPress admin panel. Here, you’ll find information about your PHP version and recommendations for upgrading to the latest version.

Upgrading to the latest PHP version can significantly improve your site’s speed and performance. It’s recommended to use PHP 7.4 or higher, as it offers significant performance improvements over earlier versions.

If your web host doesn’t support the latest version of PHP, you may need to consider changing your hosting provider that offers more up-to-date software.

Optimize Your WordPress Database to Speed Up a Slow WordPress Backend


Over time, your WordPress database can become bloated with unnecessary data, which can slow down your site’s performance. Optimizing your WordPress database can help to remove this unnecessary data and improve your site’s speed.

There are several ways to optimize your WordPress database, which can improve the speed of the WordPress dashboard. The first step is to make a backup of your database, so you can restore it if anything goes wrong. You can use a plugin like UpdraftPlus to create a backup of your database.

Next, you can use a plugin like WP-Optimize to clean up your database. This plugin can remove unnecessary data like post revisions, spam comments, and transient data. It can also optimize your database tables to improve performance.

In addition to using a plugin, you can also manually optimize your database by using phpMyAdmin. This involves running SQL queries to remove unnecessary data and optimize your tables.

Database optimization should be done carefully, as deleting the wrong data can cause issues with your site. So, make sure to create a backup before optimizing your database and proceed with caution.

Limit or Disable the WordPress Heartbeat API


The WordPress Heartbeat API is a feature that allows your browser to communicate with the server and check for new content. While this feature is useful, it can also cause performance issues on some sites, especially those with a large number of logged-in users.

If you’re experiencing slow WordPress backend, one of the solutions is to limit or disable the WordPress Heartbeat API. There are several ways to do this.

The easiest way is to use a plugin like Heartbeat Control. This plugin allows you to control how often the WordPress Heartbeat API runs and where it runs. You can set it to run less frequently or disable it entirely.

Another option is to modify your theme’s functions.php file. You can add a code snippet to limit the Heartbeat API to specific pages or disable it entirely.

You should note that disabling the Heartbeat API can affect some plugins and features, such as autosave and real-time updates. So, make sure to test your site thoroughly after making any changes to the Heartbeat API.

Increase WordPress Memory Limit in the WordPress Admin Panel

When you’re running a WordPress site, it’s important to make sure that your site has enough memory to function properly. If your site doesn’t have enough memory, it can cause slow WordPress backend and other performance issues.

One way to solve this problem is by increasing your WordPress PHP memory limit. By default, WordPress sets the memory limit to 32 MB, but you can increase it to a higher value based on your site’s requirements.

To increase your WordPress memory limit, you can add a code snippet to your site’s wp-config.php file. This file is located in the root directory of your WordPress installation.

Here’s the code snippet you can use:

define(‘WP_MEMORY_LIMIT’, ‘256M’);

In this example, we’re increasing the memory limit to 256 MB, but you can set it to any value that suits your needs.

Not all web hosts allow you to increase your WordPress memory limit. So, if you’re not able to increase the memory limit through the wp-config.php file, you may need to contact your web host for assistance.

Change Your Hosting Provider

If you’ve tried all the previous solutions and you’re still experiencing slow WordPress backend, it may be time to consider changing your hosting provider. Your hosting provider plays a critical role in determining the speed and performance of your WordPress site.

There are several factors to consider when choosing a hosting provider. First, you want to make sure that they offer reliable and fast servers. Look for hosting companies with a good reputation and positive reviews from other WordPress users.

Checkout Seahawk’s WordPress Host Reviews And Ratings, where we’ve reviewed top web hosting services for you to make the right choice.

Another factor to consider is the type of hosting plan that you’re using. Shared hosting plans are often the cheapest option, but they can also be the slowest. If you’re experiencing slow WordPress backend, consider upgrading to a VPS, dedicated server or Cloud hosting, which can provide faster and more reliable performance. Or better yet, opt for specialized WordPress hosting.

You should also look for a hosting provider that offers good customer support. If you ever run into issues with your site, you want to be able to contact your hosting provider for help and support.
