Is your WordPress site and admin dashboard running slower than you expected it to? If this is an issue you’re facing, you’ll want to consider different solutions to help optimize your experience and improve overall performance. 

In this article, we’ll teach you about different ways you can improve your WordPress site and admin dashboard’s optimization.

Test WordPress Site and Dashboard Performance

Before changing anything about your site or admin dashboard page, you should measure your WordPress site and admin dashboard’s speed so you can compare and identify any future improvements to your site’s performance. Thankfully, this can be done relatively easily thanks to desktop browsers having built-in tools that check site performance. For example, if you’re using Google Chrome, you can simply right-click anywhere on the page to open the Inspect tool on your site. From here, find the “Lighthouse” tab in the new interface that appears, and click the “Generate Report” button below the Lighthouse image. This lets you generate a report where you can see what your WordPress site and admin dashboard is being slowed down by. You can then use this information to guide your next steps in improving performance based on your individual needs.

Install WordPress Updates

49.07% of WordPress sites aren’t running the latest version of WordPress, and 33.58% of WordPress sites are at least 2 updates behind the latest version. While many people may not keep their WordPress sites up to date with the newest version, there are notable benefits to their site’s performance that they’re missing out on. WordPress updates can include optimization updates to WordPress’s features and coding, speed and security improvements, bug fixes, and more. This means you can improve your site’s overall performance simply by adapting this newer version. 

To install WordPress updates, simply enter the “Updates” page under the “Dashboard” tab in your WordPress dashboard menu, then install any updates you see. The same process is used for WordPress plugin and theme updates.

Delete Inactive Plugins

It’s common for WordPress sites to have a lot of plugins installed on them. While many may be installed, a good portion of these plugins might be inactivated, meaning they’re turned off but are still installed on the site. It’s best practice to delete these unused plugins to improve your site’s performance. Even if plugins are inactive and disabled, they still take up resources and memory on your site, which can slow down your site’s performance. The solution to this is to simply delete your unused plugins to maximize more available resources going to other parts of your site that matter.

Enter the “Installed Plugins” page under the “Plugins” tab in your WordPress admin dashboard menu. You can only delete inactivated plugins, so under any active plugins you’d like to delete, click the “Deactivate” option to do so. Then, under any inactivated plugins, simply click the “Delete” option below the plugin’s name. WordPress will ask you for confirmation for this deletion, so click the “OK” option to proceed, and the plugin will be safely removed and uninstalled from your site.

Unused but not-deleted plugins can also be potential security liabilities. Loopholes and weaknesses in their code could mean danger against the safety of your site. Be sure to delete unused plugins, not just to improve site performance, but also to ensure safer site security.

Update Your PHP Version

WordPress runs on a programming language known as PHP. When PHP is updated, its functions and performance improve, and as a result WordPress sites also benefit from these alterations once their version of PHP is updated. Using the latest version of PHP means your site receives significantly improved performance, and not updating means you’re missing out on performance improvements. 

If you’d like to check your current PHP version, click “Site Health” under the “Tools” tab in your admin dashboard menu. Click into the “Info” tab, and look for “PHP version” in the “Server” section. If you need to update your version, it’s relatively straightforward to update your PHP version. The specific steps vary depending on your web hosting provider, but in general, you may enter your hosting control panel, which could be something like cPanel, and look for an option indicating itself to be something like a PHP Manager or PHP Management System. From here, you’ll be able to select the PHP version you’d like your site to run on. 

It’s important to note that some WordPress themes or plugins with longer histories of operation might not be compatible with newer PHP versions due to their creators not having updated them to be compatible yet. Incompatibility between updated PHP versions and themes or plugins can be worked around by lowering your site’s PHP version so that both PHP and the themes or plugins in question are compatible.

Increase Your PHP Memory Limit

Your site needs memory to smoothly operate itself and all its associated plugins and features simultaneously. If you don’t have enough memory available for PHP and WordPress to operate with, it might slow down and even crash your entire site. Often, more data-heavy sites like those with long pieces of writing, many images, active forms, or process-heavy plugins, all of which use lots of data, have a need for more memory than typical sites do. 

The good news is that there’s typically more than enough memory allocated to sites’ functioning. To see your PHP memory limit for yourself with WordPress, start by finding the “Tools” tab in your admin dashboard menu and clicking on “Site Health”. From there, enter the “Info” tab and look for “PHP memory limit” under the “Server” section. For a typical site, a memory limit of 128MB is more than sufficient and will support the site’s functions with little to no issue. 

With Doteasy, your PHP memory options can be found by entering your cPanel interface once you’ve logged in. Find and click into the “MultiPHP INI Editor” page. From here, choose the domain that you want to edit the PHP configuration for. You’ll then be able to directly tweak your memory limit based on your site’s needs.

Install Caching Plugins

WordPress caching plugins help you optimize page load speed, CSS and JavaScript delivery, your WordPress database, and more. They’re vital to improving website speed, and can also help you fix slow-loading admin dashboard pages. These processes help free up resources on your WordPress hosting server, so your site and admin dashboard page can utilize them for improved performance. We recommend WP-Optimize, an all-in-one plugin that caches and optimizes your site’s content. To use WP-Optimize once it’s been installed, start by finding the “WP-Optimize” tab in your admin dashboard menu. Enter it and then click “Run all selected optimizations” to optimize your WordPress database.

Reduce WordPress Dashboard Widgets

Upon opening your admin dashboard page, both WordPress itself and many plugins you might have installed automatically load widgets onto your dashboard. While they may be informative or helpful, they can also greatly slow down your site and admin page. The solution to this is to reduce the widgets that run on your dashboard page. You can do this manually by finding and clicking on the “Screen Options” button on your “Dashboard” page, then uncheck any ticked boxes next to widgets you don’t want appearing anymore.

Fix Slow WooCommerce Dashboard

WooCommerce has features that can slow down your admin dashboard page’s performance. When you’re customizing the widgets in your WordPress admin dashboard, click on the “Screen Options” button in your “Dashboard” page, then uncheck any ticked boxes next to widgets that you don’t want appearing anymore. Also, WooCommerce supporting a store on your site might add unneeded data to your site’s database over time that can slow down your site, which is a problem you can solve simply with a plugin. Using the WP-Optimize plugin, you can enter its tab in your admin dashboard menu, where you can optimize your WordPress database however you wish to. Simply press the “Run all selected optimizations” afterwards to optimize your site’s database.

Lock WordPress Admin and Login Pages

DDoS attacks and hacking attempts are common problems faced by WordPress sites and their owners. Particularly, brute force attacks are the most common form of malicious attempt against WordPress sites. In brute force attacks, attackers submit hundreds of passwords at once in hopes of eventually guessing correctly and gaining access to the site.

Brute force attacks may not take down your site, but are very likely to slow down and limit access to your website. This is why we recommend installing Loginizer, a plugin that helps you tackle problems from brute force attacks by limiting login attempts to only 3 tries before blocking the IP address of the attempts. It’s also able to blacklist and/or whitelist IPs that try to log in. Because of how vital plugins like Loginizer are in defending against security threats, Doteasy’s WordPress hosting gives users the option to install this plugin alongside their initial WordPress installation. 

Additionally, it’s important to rename the default “wp-admin” login URL. This URL is the default login URL used across all WordPress websites and is widely known to cybercriminals, so keeping this login URL unchanged means your site is more at risk of being brute force attacked. We recommend installing a lightweight plugin called Lockdown WP Admin, which lets you hide the “wp-admin” URL, and lets you customize your own unique login URL as well. This means that instead of having the typical login URL of that anybody could find, you need to access,, or any other URL you can think of that only you would know of, in order to try to log in. This would enhance your site security to make it harder for malicious attackers to find and attack your site’s login page.

Upgrade Your Hosting Plan

As websites grow in size, such as receiving more traffic, hosting more content, and needing more resources, you might notice slow or subpar site performance becoming an issue. This indicates that you have likely outgrown your current hosting plan, which you had bought before the growth of your site. The solution to this issue is to simply upgrade your hosting plan so that your site benefits from faster and more powerful hosting infrastructure. Your site will receive the power and support it needs to accommodate what you and site visitors expect from it. With Doteasy, we offer a wide range of hosting plans ranging from simple starter plans to advanced high-performance plans with more server resources like CPU, memory, and higher I/O speeds with SSD storage, so contact us if you have any questions about what hosting plan is right for you. 

There are a wide range of ways to improve your website’s performance. With the solutions covered in this article, the improvements you see should be noticeable, and help you optimize your site to run faster and smoother.
