WordPress backend is slow? Causes and solutions

The slow backend speed of WordPress will seriously affect the efficiency of website management. Here are common reasons and targeted solutions:

Cause: Database bloat

Over time, WordPress databases increase as they store unused comments, revisions, and plug-in data.

Solution: Optimize the database

Use plugins such as WP-Optimize or manually delete unnecessary tables and entries.

Reason: Theme or plug-in is inefficient

Some themes and plugins will increase page loading time.

Solution: Check the theme and plugins

Disable unnecessary or inefficient themes/plugins. Consider using lightweight themes and plugins.

Cause: Image not optimized

Large images are not optimized to slow down page loading.

Solution: Optimize images

Use plug-ins such as Smush Image Compression and Optimization or use online tools to compress images.

Cause: Too many HTTP requests

When the page loads, WordPress sends multiple HTTP requests to load CSS, JavaScript, and image files.

Solution: Merge and minify files

Merge and shrink CSS, JavaScript, and HTML files using plug-ins such as Autoptimize.

Cause: Web hosting issues

The performance of the managed server can affect the speed of the WordPress backend.

Solution: Upgrade hosting services

Choose a hosting provider that provides fast and reliable servers.

Cause: The cache is not enabled

Caching technology can significantly improve page loading speed.

Solution: Enable caching

Use a plug-in such as W3 Total Cache or contact the hosting provider to enable caching.

Cause: Spam attack

Spam comments and pingbacks consume server resources and slow down WordPress.

Solution: Prevent spam

Install an anti-spam plug-in (such as Akismet) and disable pingback in WordPress settings.

Cause: Malware infection

Malware can infect WordPress websites and cause the background to slow down.

Solution: Scan the malware

Use security plugins such as Wordfence to scan and remove malware.
