How to fix a slow WordPress Admin Dashboard?

Upgrading Hosting

Poor hosting is one of the main common issues for the slow WordPress admin dashboard. This may not be the actual reason for your specific site. When your hosting is overloaded more, you will experience problems. The site becomes slow due to poor overloaded hosting.

Some of the popular hosting providers are Dreamhost, Bluehost, Hostinger, CloudWays, GoogleCLoud, etc. You can use any of them but keep in mind hosting services must be good. If you have enough money to pay then my recommendation is CloudWays.

Avoid Slow and Heavy Plugins

Heavy plugins and unoptimized plugins might slow down the WordPress dashboard. You may have noticed that when you have fresh install WordPress, the admin panel loads fast. But later after installing some plugins, it slows down slowly. More plugins do not slow down the website. It’s those heavy and unoptimized plugins that slow down the website.

To check which plugins cause slow dashboard loading, we recommended installing the free plugin Query Monitor. You can later uninstall that plugin so no need to worry about that. Install the plugins and later you will notice a new option in WordPress Toolbar. Click that new option to open the plugins interface and go to Queries by the Component tab. Take a look at any slow plugins.

If you find any slow plugins, deactivate them and delete them if possible. Search for the alternative plugins for those plugins if you need the features provided by the slow plugins.

Upgrade PHP Version

Since WordPress is built from PHP so the version of PHP also plays a vital role in the site performance and admin panel performance. The higher the PHP version more the security and performance.

You may be one of those who are using WordPress with a PHP version lower than 5.6. In 2020, the recommended version for PHP is 7.3 or more than that. Try manually upgrading the PHP version in the hosting panel. If the hosting provider does not allow those features to you, try contacting the hosting provider to upgrade the PHP version.

Consider Removing Bloatware From WordPress Dashboard

There are many preinstalled bloatware in WordPress which you may not need. So removing that bloatware is an effective solution. More than 90% of the WordPress bloatware can be removed by using the Perfmatters Plugins developed by Kinsta.

Disable that bloatware which you did not use anymore.

Use HeartBeat Control

WordPress API helps to provide real-time communication between your specific site and the webserver. It notifies you about the other users who are editing a post, autosave feature while writing. Since it is real-time communication, it slows down your dashboard while working by sending more requests. You can reduce the request in the admin panel by three main methods.

i) If you have already WP Rocket plugins installed in your WordPress then enable control heartbeat from the HeartBeat Tab in the WP Rocket dashboard.

ii) If you don’t have WP Rocket, then install HeartBeat Control Plugin Developed by WP Rocket developer. Once you install and activate the plugin, go to Settings, HeartBeat Control Settings to reduce the requests or disable HeartBeat API.

iii) If you don’t will to add more plugins and want to reduce API requests, then add the following function’s code in the functions.php file of the current theme.

// Disable HeartBeat API Request
add_action( 'init', 'stop_heartbeat', 1 );
function stop_heartbeat() {

Consider Optimizing Database

There can be junk files in the database that can slow down your WordPress Dashboard. So cleaning the database is necessary. You must frequently clean the database to avoid junk files. You can use plugins like WP Rocket or WP-Optimize to clean those junk files.

These plugins will delete spam comments, trash comments, all transients, revisions, and trashed posts according to your need. You usually don’t need these so delete them. You can also schedule Automatic CleanUp according to your need.

Use CDN to Offload Resources

CDN lightens the load on your server so using CDN is an effective way. I would recommend Cloudflare as it provided free global CDN to you. Don’t forget to add these 3 pages rules after setting up Cloudflare.

Page Rule 1: Cache Everything for the main domain
Page Rule 2: Bypass cache for a preview post
Page Rule 3: Bypass cache and Secure WordPress Admin Login. Don’t forget to disable performance and cache.

1) www.yourdomain.com/*
2) www.yourdomain.com/*preview=true*
3) www.yourdomain.com/wp-admin/*

Change System Status of WordPress

Sometimes your website admin panel becomes slow due to the limited memory bandwidth. Make sure to increase the memory limit, if it is the issues that slow the WordPress admin dashboard.

You can increase the memory limit by adding this line to the wp-config.php file located in the root directory of WordPress.

define( 'WP_MEMORY_LIMIT', '256M' );

If your host does not let you increase manually, try contacting them and asked to do it for you.

Limit Content Display In WordPress Dashboard

You can limit the number of content like posts, pages to display at a time. By default, the value is 20. If you have increased the number of content to show at a time, try reducing it to 15-20 to avoid a slow WordPress Admin dashboard.

You can change the content number by Using Screen Options in the top right of the WordPress Admin dashboard.

Block Spam Bots From Your Server

Many spam bots may hit your server and consume more server resources. It’s only a waste of bandwidth so kicked them out of your server. There are many plugins to kicked them. Among them, Wordfence is the best. It automatically blocks the spam bot from your server.
