This is a utility plugin for backporting a minor performance improvement scheduled for inclusion in WordPress 6.6 to earlier versions.
In WordPress 6.4 the function <code>wp_prime_option_caches()</code> was introduced to allow for multiple options to be queried in a single database call.
On sites without a persistent cache, temporary transients are stored in two options. One containing the transient itself, the other containing the timeout. These are stored as <code>_transient_[transient name]</code> and <code>_transient_timeout_[transient name]</code>.
In WordPress 6.6 and later, these options are primed by a single database call using the priming function. This plugin can be used on WordPress 6.4 and 6.5 to backport the functionality.
While a mild improvement on sites making limited use of transients, this can significantly reduce the number of database queries on sites running plugins making heavy use of transients.

This plugin cleans every transient from database older than one minute using safe native WordPress function. It works on multisite too.
By default, it will check for expired transients once daily, though you can call it any time using <code>Clean_Expired_Transients::clean();</code>.
Clean Expired Transients is a very lightweight, it has no settings, just activate it and it works immediately.
Note that it can be used by developers in their project in any place, it doesn’t require activation and it’s safe to use since it checks is there existing installation, just include it.
