Hyper Admin Speed ULTRA applies aggressive performance policies to the WordPress admin area.
Instead of adding UI features, this plugin improves perceived speed by restricting external dependencies and background processes.
It works by:
<ul>
<li>Removing externally loaded scripts and styles inside wp-admin</li>
<li>Blocking external HTTP requests from the admin environment</li>
<li>Disabling WordPress cron requests</li>
<li>Disabling the Heartbeat API</li>
<li>Applying a strict Content Security Policy header</li>
<li>Replacing Gravatar with a local avatar</li>
<li>Cleaning up default dashboard widgets</li>
</ul>
⚠️ Important
This plugin is designed for advanced users and developers only.
Because it blocks external connections and background processes, it may:
<ul>
<li>Prevent plugin and theme updates</li>
<li>Break third-party plugins relying on remote APIs</li>
<li>Disable scheduled tasks</li>
<li>Interfere with plugins that require Heartbeat API</li>
<li>Affect dashboards that depend on remote content</li>
</ul>
Do not use this plugin on production sites unless you fully understand these consequences.
