Here's a comprehensive guide on common causes and optimisation tips for WordPress and Magento admin panel performance issues. #### **Common Causes of Slow Admin Panels** 1. **Excessive Plugins or Extensions** Running too many or poorly optimized plugins (WordPress) or extensions (Magento) can slow down the backend significantly. 2. **Inefficient Database** A bloated or unoptimized database can increase response times, especially when handling large datasets. 3. **Low Server Resources (CPU/RAM)** Insufficient CPU or memory resources can severely affect admin panel performance, especially during high-traffic periods or bulk operations. 4. **Outdated PHP Version** Running on an older PHP version can degrade performance, as newer versions bring significant speed improvements. 5. **Admin Panel Caching Disabled or Misconfigured** Lack of proper backend caching leads to redundant queries and page loads, increasing load times. 6. **High Traffic on the Frontend** High server resource consumption by frontend visitors can slow down the admin panel. 7. **Cron Jobs** Overlapping or inefficient cron jobs can hog resources, causing the admin panel to slow down. #### **Optimization Tips** ##### **1. Disable or Remove Unnecessary Plugins/Extensions** Deactivate and remove any plugins you no longer use. Prioritize quality over quantity, as fewer plugins mean less resource consumption. ##### **2. Optimise the Database** Use plugins like **WP-Optimize** or **Advanced Database Cleaner** to clean up post revisions, transient options, and unused data. **Magento:** Run the built-in database maintenance tools via the Magento CLI (`bin/magento setup:db:status`) and regularly clean the `log_` tables, quote tables, and catalogue URL rewrites through **System \> Tools \> Database Log Cleaning** in the admin panel.   ##### **3. Increase PHP Memory Limit** Adjust the `memory_limit` value in your hosting’s PHP settings to a higher value, such as 256M or 512M, especially for large sites. [Guide located here](https://knowledge.blakemarkproductions.com/changing-your-php-version-php-extensions-php-functions-and-php-options) ##### **4. Update PHP to a Higher Version** WordPress and Magento perform significantly better on up-to-date PHP versions. Update to the latest stable PHP release supported by your platform via your cPanel.

Enable Admin Panel Caching** Use plugins like **LiteSpeed Cache** to enable object and database caching. **Magento:** Enable built-in caching by navigating to **System \> Tools \> Cache Management** and enabling all cache types. For object caching, configure Redis via your server settings for improved backend performance. ##### **6. Use a Content Delivery Network (CDN)** Offloading static assets (CSS, JS, images) to a CDN reduces server load, improving both frontend and backend performance. ##### **7. Optimise Cron Jobs** **WordPress:** Offload WP cron jobs to a server-side cron by completing these two steps: 1. Add `define('DISABLE_WP_CRON', true);` to your `wp-config.php` file. 2. Set up a replacement cron job in cPanel. **Magento:** Ensure the Magento cron is configured correctly via cPanel or CLI (`bin/magento cron:install`). Review and resolve any stuck or overlapping cron jobs under **System \> Cron (Scheduled Tasks)** in the admin panel to prevent resource exhaustion. `define('DISABLE_WP_CRON', true);` to your wp-config.php and setting up a proper cron in cPanel. [Guide located here](https://knowledge.blakemarkproductions.com/how-to-disable-the-wordpress-cron-job-and-set-it-up-in-cpanel) ##### **8. Limit Admin Panel Resource Usage** Use plugins like **Heartbeat Control** to reduce or control the frequency of admin-ajax requests that can drain server resources.   ##### **9. Reduce Concurrent Backend Users** Too many users logged into the admin simultaneously can slow it down. Consider limiting access during high-demand times. ##### **10. Monitor Real-Time Resource Usage** Use monitoring tools to check if the admin panel slowdown is linked to server resource spikes. **Magento** users can enable the built-in Magento Profiler (`bin/magento dev:profiler:enable`) or use New Relic integration (if available on your hosting plan) to identify slow queries and admin panel bottlenecks. WordPress users can use **Query Monitor** to identify slow queries and performance bottlenecks. - [Getting Started](https://help.blakemarkdigital.co.uk/getting-started) - [Web Hosting](https://help.blakemarkdigital.co.uk/web-hosting#main-content) - [Elementor](https://help.blakemarkdigital.co.uk/web-hosting#elementor) - [WordPress](https://help.blakemarkdigital.co.uk/web-hosting#wordpress) - [Security](https://help.blakemarkdigital.co.uk/web-hosting#security) - [Email](https://help.blakemarkdigital.co.uk/email#main-content) - [Mail Clients](https://help.blakemarkdigital.co.uk/email#mail-clients) - [SpamExperts](https://help.blakemarkdigital.co.uk/email#spamexperts) - [MailChannels](https://help.blakemarkdigital.co.uk/email#mailchannels) - [Domains](https://help.blakemarkdigital.co.uk/domains#main-content) - [Domain Privacy](https://help.blakemarkdigital.co.uk/domains#domain-privacy) - [Billing](https://help.blakemarkdigital.co.uk/billing) - [cPanel](https://help.blakemarkdigital.co.uk/cpanel#main-content) - [JetBackup](https://help.blakemarkdigital.co.uk/cpanel#jetbackup) - [Softaculous](https://help.blakemarkdigital.co.uk/cpanel#softaculous) - [WordPress Glossary Terms](https://help.blakemarkdigital.co.uk/wordpress-glossary-terms#main-content) - [H](https://help.blakemarkdigital.co.uk/wordpress-glossary-terms#h) [![Blake Mark Digital Logo](https://help.blakemarkdigital.co.uk/hs-fs/hubfs/Asset%205.png?width=250&height=71&name=Asset%205.png "Blake Mark Digital Logo")](https://blakemarkdigital.co.uk/) Blake Mark Digital is a digital marketing agency supporting SMEs and non-profits with strategic branding, content, and campaigns that drive real results 124-128 City Road, London, EC1V 2NX [support@blakemarkdigital.co.uk](mailto:support@blakemarkdigital.co.uk) +44 20 4578 9582 [mailto:support@blakemarkproductions.com](mailto:support@blakemarkproductions.com) Copyright © Blake Mark Productions Ltd
