Pagoda Panel WordPress Build Server Cache Optimization

PHP version: At least version 7.0 or above should be chosen, and version 7.3 is recommended because of its better performance. If your website theme is compatible, try upgrading to PHP 7.3.

Cache:

• Opcache: This is a caching tool that must be installed after installing PHP, it speeds up PHP scripts and is a basic setting.
• Memcached: It is also necessary to support more advanced features that keep data in memory, making data access faster.
• Redis: This is a memory-based but persistence-enabled key-value database, mainly used for caching, with no compatibility issues, so it's highly recommended to install it, even if you don't use it for a while.
• Imagemagick: This is a high-performance image processing library, almost all websites use images, so this library is also a must install.
• Other PHP extensions: Install as you need, but for general website building, the few mentioned above should suffice.
