Widget Output Cache
v0.5.3 · by Kaspars
Improve website performance by caching widget output in WordPress transients.
About this plugin
Use PHP output buffering to extract widget output and store it into WordPress transients for faster retrieval. It also adds a checkbox to widget controls to exclude it from being cached.
It is a quick fix for bad behaving plugins that parse RSS feeds or call remote URLs on every page load.
Note that the plugin supports only Classic Widgets — the caching does not apply to widgets rendered in the block-based editor.
