How to Set Up Performance Booster in Plesk

Performance Booster is a Plesk extension that helps optimize your website’s performance with built-in caching and speed tools — especially helpful for WordPress and PHP-based sites.

Step 1: Log in to Plesk

Go to:

https://your-server-ip:8443

Log in with your Plesk credentials.

Step 2: Install Performance Booster Extension (if not yet installed)

• Go to Extensions in the left menu

• Click Extension Catalog

• Search for Performance Booster

• Click Install

Once installed, it will appear under the domain’s tools.

Step 3: Open Performance Booster

• Go to Websites & Domains

• Choose your domain

• Click on Performance Booster from the available tools

Step 4: Enable Performance Features

Depending on your server and setup, you may see options like:

• NGINX caching or Microcaching

• Opcode caching (OPcache)

• Static file caching

• Brotli or GZIP compression

• HTTP/2 support

• PHP-FPM tuning

• Redis or Memcached integration (optional)

You can toggle these features individually, or click "Enable All" for default optimization.

Step 5: Test Your Website Speed

Once activated:

• Visit your site and check speed improvements

• Use tools like GTmetrix or PageSpeed Insights to compare before and after

Optional: Customize Settings for WordPress

If you’re using WordPress, the Performance Booster may auto-detect it and offer special tuning:

• Enable WordPress caching rules

• Integrate with Plesk WordPress Toolkit for further optimization

Step 6: Monitor and Adjust

If needed, you can fine-tune specific features depending on your app:

• Disable compression for already-optimized files

• Increase memory limits for PHP apps

• Add cache exceptions for admin or dynamic pages
