A sluggish WordPress Admin experience isn’t just frustrating, it can disrupt your workflow, delay content publication, and hurt overall website performance. If your WordPress dashboard feels clunky or unresponsive, you’re not alone. Many site owners face similar issues, especially when using outdated dashboard templates or resource-heavy plugins.

In this guide, you’ll discover proven, real-world techniques to identify and fix a WordPress Slow Dashboard. From optimizing server resources to improving dashboard UI performance, we cover every aspect to ensure a smooth and fast admin experience.

Why is a WordPress Dashboard Being Slowed Down?

A WordPress dashboard slows down mainly due to limited server resources as your site traffic and content grow, increasing server load. The admin area is uncached by default, making it more resource-intensive than the front end.

Other causes include resource-heavy or outdated WordPress plugins, excessive dashboard widgets, outdated PHP or WordPress versions, and inefficient hosting. These factors consume memory and processing power, causing slow responsiveness in the backend

There are several root causes behind a slow WordPress admin, including:

  • Limited server resources (CPU and memory)
  • Outdated WordPress core, themes, or dashboard templates
  • Heavy database queries from inefficient WordPress plugins
  • PHP version incompatibilities
  • Excessive dashboard widgets or frequent autosave requests
  • Lack of object caching or back-end optimization

Even if the front-end of your website loads quickly, the WordPress admin dashboard is a dynamic environment. It doesn’t benefit from front-end caching and thus requires additional optimization efforts.

We offer extraordinary WordPress themes and templates that are built for speed, security, and top-tier performance—perfect for any modern website.

13 Proven Ways to Speed Up a WordPress Slow Dashboard

Each step below includes practical advice backed by real experience optimizing dozens of WordPress sites.

1. Audit Your Admin Performance (Lighthouse + Query Monitor)

To fix a slow WordPress dashboard, you first need to identify what’s causing the delay. Start by auditing your admin area using tools like Chrome Lighthouse and the Query Monitor plugin. These tools help uncover backend performance issues—such as slow database queries or plugin conflicts—so you can make informed optimization decisions.

Start by measuring the current performance of your admin area.

  • Use Chrome Lighthouse via Developer Tools to analyze backend rendering performance.
  • Install Query Monitor to analyze database queries, hooks, and memory usage.

👉 Real example: On a WooCommerce site with 15+ plugins, Query Monitor flagged a product filter plugin adding 2.4 seconds to load time.

1. Audit Your Admin Performance (Lighthouse + Query Monitor)

If you do this, your browser screen will split into two, and you will see the Inspect area in one of the windows, either at the bottom or on the side of your browser window.

Click the Generate Report button under the Lighthouse tab in the Inspect tool.

The Page Speed Insights report will be generated similarly to the Web Vitals report.

With this tool, you can see what’s making your WordPress admin area slow. It allows you to see which JavaScript files are using more resources and affecting your server’s initial response speed.

2. Update WordPress Core, Plugins & Themes

Update WordPress Core, Plugins & Themes

Outdated WordPress installations can slow down your admin panel and expose your site to bugs. Each WordPress release brings performance boosts and security fixes, while updated WordPress themes ensure smoother compatibility. Always keep your core, plugins, and themes updated to avoid unnecessary dashboard lag.

  • Navigate to Dashboard > Updates
  • Remove outdated or unsupported plugins

Pro tip: Use a staging site to test updates before applying them to your live site.

3. Upgrade PHP to the Latest Stable Version

PHP, an open-source programming language, is used to develop WordPress. PHP version 7.4 or higher is required for WordPress at the time of writing this article. As of today, PHP is available in version 8.1.6, which is stable.

  • Check PHP version in Tools > Site Health > Info Tab
  • Use cPanel or your hosting provider dashboard to upgrade

There is a good chance that most WordPress hosting companies do not use the latest PHP version out of the box, as they maintain the minimum requirements required to run WordPress.

Like WordPress, PHP is now released with new versions that make considerable improvements to performance. This performance boost is not available with an older version.

Using the Tools > Site Health page in your WordPress dashboard and selecting the ‘Info‘ tab, you can see which PHP version your hosting provider uses.

check-php-version

Fortunately, every reliable WordPress hosting provider offers an easy means of upgrading its PHP version.

Impact: PHP 8.2 can handle up to 50% more requests per second than PHP 7.4.

Bluehost, for instance, has an Advanced tab in the left column of their hosting control panel.

multiphp

Under the Software section, you will find MultiPHP Manager.

Next, you must choose the PHP version you want to use and your WordPress blog.

change php version

4. Increase PHP Memory Limit

WordPress recommends a minimum of 256MB, but 512MB or more is ideal for busy dashboards.
Add this to your wp-config.php:

  • define(‘WP_MEMORY_LIMIT’, ‘512M’);

Check the current memory under Tools > Site Health > Info.

check php limit

5. Use a Caching Plugin (Object + Page Cache)

Caching plugins for WordPress not only speed up your site but also speed up your admin dashboard.

You can optimize your WordPress database, CSS, and JavaScript delivery, and page loading speed with a WordPress caching plugin.

As a result, your WordPress admin area can better utilize the resources on your WordPress hosting server.

While admin pages aren’t cached like front-end pages, object caching still helps.
Recommended plugins:

  • WP Rocket (premium)
  • LiteSpeed Cache (for LiteSpeed servers)
  • W3 Total Cache with Redis or Memcached

6. Check and Monitor WordPress Plugins Performance

Within WordPress’s admin area, some plugins can be run. WordPress admin areas can easily sluggish down if plugin authors don’t take care when creating plugins.

Installing the Query Monitor plugin will help you find such plugins. We have a step-by-step guide on installing a WordPress plugin that provides more details.

A new menu item will appear in your WordPress toolbar when the plugin is activated.

querymonitor tab - Check and Monitor WordPress Plugins Performance

When you click it, performance results will be displayed for the page you are currently viewing.

If you click it again, Query Monitor will appear.

Here, you need to turn to the left side tab ‘Queries by Component’. It allows you to see how plugins affect performance so you can identify which one is taking up too many resources.

The slow plugins can now be temporarily disabled to see if performance improves.

If that is the case, it will be possible for you to reach out to the plugin author for support or look for an alternative plugin.

7. Check the WooCommerce Dashboard and Fix the Slow-loading

You may notice that the performance of your WordPress admin area is affected if you run an online store using WooCommerce.

By adding a menu item to the screen options, you can disable the dashboard widget for WooCommerce.

Similarly, you can modify the Product page information.

The database of your WordPress website might fill up with unnecessary data from your WooCommerce store after a while.

8. Twisting Admin Screens and Disabling Dashboard Widgets

Several widgets are automatically loaded on the dashboard when WordPress is activated. The widgets include- Quick Draft, Site Health, Events and News, and many more.

Some WordPress plugins come with their widgets that add to the WordPress admin dashboard screen. As a result, having these kinds of so many widgets, your dashboard loading speed will surely become slow.

So, you need to turn off these widgets. To do so, click on the Screen Options button and uncheck the box you want next to the widgets.

Similarly, the Screen Options option allows you to display and hide sections on other admin panels.

On the posts screen, for example, you may specify which columns to display.

9. Controlling WordPress Autosave Feature

With WordPress, the block editor features an autosave feature. In case you don’t save your changes and close the editor, it allows you to easily restore your content.

While all those autosave requests may not slow down your WordPress admin area, if multiple users are working on your website at peak traffic times.

As a result, we do not recommend disabling autosave. Instead, you can reduce its speed to save performance.

In your wp-config.php file, add the following line.

define( 'AUTOSAVE_INTERVAL', 120 )

In this line, WordPress is told to run automatic saving every two minutes (120 seconds) rather than once.

10. Reducing API calls for the Heartbeat API

With the heartbeat API, WordPress can send Ajax requests to a server without having to reload the page. This allows plugin developers to show you notifications in real-time and lets authors know when posts are being edited by other users.

Plugin developers ping the API once every 60 seconds. As multiple authors work on the same website at once, these resource-heavy server calls may become an issue.

The Heartbeat Control plugin is also an alternative you can use to reduce Heartbeat API calls.

If possible, we recommend that you reduce API calls by at least 120 seconds.

11. Blocking WordPress Admin Directory and Login Pages

WordPress websites are vulnerable to random hackers and DDoS attacks.

WordPress login pages are accessed, and hundreds of login attempts are made within a short period of time by these automated scripts.

Despite not being able to access the WordPress site, they will still be able to slow it down.

Your WordPress Admin folder and login pages can be secured with a password, which is an easy and straightforward way to block these scripts.

You can simply switch to the Advanced Tab in your hosting control panel if you are on Bluehost. In the Directory Privacy section, click on it.

directory privacy

The next step is to locate the wp-admin directory (usually located in the public_html folder).

You can then edit it by clicking the Edit button below.

wp admin directory

In the next step, you will be asked to give your protected directory a name.

name folder

To continue, click on Save. To continue, you will have to click the Go Back button for the control panel to save your changes.

To access the protected folder, you must first create a username and password.

create username password

You will now need to enter your username and password when you visit your WordPress admin area.

login prompt

12. Create a Password-Protected WordPress Login Page

As a next step, you would like to block access to the WordPress login page. The only way to do this is to edit your website’s .htaccess file manually and generate a password file.

Using an FTP client or your hosting control panel’s File Manager, connect to your WordPress website.

Go to the directory of your website (the directory is where your wp-admin, wp-includes, and wp-content files are located).

To do this, create a file named .htpasswd.

creaate htpasswd

In the following step, you will need to use the online tool to create a .htpasswd string.

Your WordPress admin directory username and password should be the same as your WordPress password.

Once that’s done, click Generate.

generate password

As soon as you run the tool, you will see a string of usernames and passwords.

Using the .htpasswd file you created earlier, copy and paste this string.

To do this, open your web browser and open the .htaccess file, and copy and paste the following code into it.

### BEGIN BASIC BLOCK
<Files wp-login.php>
AuthType Basic
AuthName "Protected Folder"
AuthUserFile /home/username/public_html/yourwebsite/.htpasswd
Require user jsmith
Satisfy All
</Files>
### END BASIC BLOCK

Change AuthUserFile to the path to your .htpasswd file after replacing jsmith with your own username. It should be located in the File Manager app.

13. Upgrade or Switch to a Finer WordPress Hosting

It is your WordPress hosting provider who is responsible for handling all WordPress performance issues.

In this case, you are limited to the resources your hosting provider offers to improve performance.

While the tips above will help you reduce server load on your WordPress site, they may not be sufficient in every hosting environment.

It would be best if you moved your WordPress site to a new host and signed up with a different hosting company to enhance performance even more.

Our recommendation is Bluehost, which is a top WordPress hosting company. A built-in cache improves WordPress performance on the shared hosting plans offered by them.
