1. Upgrade Your Hosting

Though it’s not a standard fix, using poor hosting is one of the reasons for your slow WordPress dashboard. Usually, there are two scenarios that lead to this issue-

  • The first one is, your host is plain and unable to provide the web hosting performance that you are looking for.
  • Another one is, you may have a quality host, but you’ve outgrown your hosting plan.

In both ways, your hosting company failed to support your website’s functionalities and almost led to a slow WordPress dashboard panel. So, if the issue is related to your hosting, it will be better to look out for a better host. But, switching to another hosting can be a frustrating mechanism; therefore, before doing it, ensure it’s absolutely required.

These are some best hosts and partners for your WordPress that you can consider-

2. Use the Latest PHP Version

Generally, WordPress is built with PHP, but the exact PHP version of your website depends on the installed PHP version on your server. The outdated PHP affects the efficiency, security, and speed of your WordPress dashboard panel. In contrast, the newer version of PHP offers more security, performance improvements over the older ones.

PHP Versions

That is why you should update to the most recent PHP version. The following images and statistics will make it more clear to you.

According to WordPress.org, only 0.81% of WordPress sites are running on the latest PHP version. What’s even worse is that more than 35% of WordPress sites run on PHP 7.2 or older versions.

According to Kinsta, the latest PHP 8.0 version can handle 233.40 requests per second. So, if you compare it to the PHP 7.0 version, the latest one can handle 50% more requests per second.

According to Kinsta

That means you may be one of that 35% who is running your WordPress on the older version and facing the slow loading speed. As you can see, there is no real benefit of using older versions. So, update your site’s PHP version through your hosting dashboard that will support the most recent releases and make your WordPress dashboard work faster. If your host doesn’t allow you to make this change, reach out to your host’s support staff for help.

3. Use Query Monitor and P3 Plugin to Identify the Resource-Heavy Plugin

When you install WordPress, it literally remains empty. But to optimize your website with more ease, flexibility, and, most importantly, saving time, you require installing plugins. Maximum people think that when they start installing more plugins, the WordPress dashboard starts to slow down.

The reality is, it’s an absolute myth. More plugins don’t really slow down your dashboard panel, “more resource-heavy plugins” do. So, you should focus on finding those resource-heavy plugins.

To find those plugins that are using more resources, you can use Query monitor or P3 (Plugin Performance Profiler). Both plugins are available in the WordPress repository.

Simply, install and activate the plugin and run a simple test to find out those heavy resources plugins. Once identifying slow plugins, consider disabling and deleting them and find out better alternative plugins.

4. Ensure Using Heartbeat Control Plugin

WordPress uses heartbeat API (admin-ajax.php), which is great for controlling auto-saving processes and managing sessions between multiple WordPress accounts. Besides, it provides real-time communication between your server and web browser while signing in to the WordPress admin.

Still, it is one of the reasons for slowing down the admin panel. The reason behind this is, when you’re working in the editor, it transmits a new AJAX query every 15 seconds or every 60 seconds in the rest of the dashboard.

To control this issue, you can use the Heartbeat Control Plugin Powered by WP Rocket. After installing and activating this plugin, go to Settings > Heartbeat Control Setting.

Ensure Using Heartbeat Control Plugin

Here, you can reduce or disable the heartbeat API for different areas of your dashboard. Consider reducing the frequency first, and go for disabling it only when reducing doesn’t work for your dashboard.

5. Clean and Optimized the WordPress Site Database

By cleaning out and optimizing the WordPress databases, you can conveniently solve the slow-loading dashboard issue. By default, WordPress databases will increase in size over time in the form of post revision, transients, etc.

If you are managing a WooCommerce store, then this can be very common for you as you will find more expired transients in the database. Fortunately, you can delete most of this data safely without affecting your site negatively. There are two tools like ManageWP and WP-Optimize.

Both these tools can help you to remove all the unwanted data from your database and manage the database size.

6. Increase the WordPress Memory Limit

Because of your WordPress site’s PHP memory limit, sometimes the dashboard faces some obstacles to run. In this case, increasing the memory limit can fix this problem (not all the time).

While some web hosts allow you to increase the PHP memory limit by yourself, some will not. If your host allows increasing the memory limit, simply add “define(‘WP_MEMORY_LIMIT’, ‘256M’); to the top of your wp-config.php file.

And, if your host doesn’t allow you to do that manually, contact your host’s support center and ask for help.

7. Limit How Much Content You Display in the WordPress Admin

For the non-techies, this option will be the easiest one to improve the loading speed of the WordPress panel. From the Screen Options settings of WordPress CMS, you can control the number of your posts, pages, and custom post types. It includes controlling things like WooCommerce products, orders, etc.

Limit How Much Content You Display in the WordPress Admin

You should remove those items which you don’t require to speed up the loading time. Use the “Next Page” option; in this way, the WordPress dashboard will require loading less content each time. When it comes to WordPress speed, always remember, less is better.

8. Disable Unnecessary Dashboard Widgets

Unfortunately, your WordPress dashboard comes with several widgets by default that you don’t need or probably never use. All these widgets make external calls to load that information, which ultimately leads your dashboard to load slow. Therefore, you should disable as many widgets as possible which you don’t require.

For this, you can use a plugin called Widget Disable, just install and activate it. After that, navigate to Appearance > Disable Widgets. You can also disable widgets that have been added by other plugins like WooCommerce.

9. Upload the Latest Version of WP-Admin and the WP-Includes

If all the above tips don’t work for your WordPress dashboard, you can attempt to upload the latest version of wp-admin and wp-includes. Download the latest version of WordPress and do the following-

  • Extract the ZIP folder.
  • Upload the wp-admin and wp-includes folders through FTP.
  • Lastly, select the overwriting the files option whenever prompted in front of your screen.

But before updating the latest WordPress version, ensure making a backup of your entire site.

Wrapping Up

A slow WordPress dashboard will still function, but it will make working with the slow panel miserable. Therefore, you should focus on optimizing your WordPress dashboard panel as soon as possible.

We have shared all the tips to fix your WordPress dashboard slow loading speed. By applying them, you can ensure speeding up both your WordPress dashboard and front-end site. We hope you enjoyed this article and get what you are looking for.
