Who Should Use APCu Manager?
This plugin is best suited for site owners and developers who have APCu enabled on their server and want to see APCu statistics in the WordPress admin. It is ideal for users running high-traffic sites or resource-intensive applications where object caching can reduce database load. The plugin works on multisite networks, with Network Admins gaining full management access and Site Admins receiving analytics reports only.
Users should have a basic understanding of caching concepts and server requirements. The plugin requires PHP 8.2+ and WordPress 6.4+. For statistics to function properly, you need a fully operational WordPress cron running at intervals of less than five minutes. This makes it more appropriate for technical users who can configure server-level caching and cron jobs.
