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 is a Multisite plugin. It can be activated only in network wide. The Surbma | Multisite Transient Cleaner plugin deletes ALL transients from ALL sites in a Multisite. So please be careful and don’t forget to backup your database before acivating this plugin!
The transient deletion only runs once, when the plugin is activated. You can leave it as is, but I strongly recommend to deactivate it and activate again, if you need so.
I don’t recommend this plugin for anybody and I don’t promise anything, this plugin can solve, it is doing, what it says: deletes ALL transients from ALL sites in a Multisite. If you need a simple way to do just this, this plugin will do the job.
