Gambit Cache Menus caches the menus that you use in your front end. This may not be much (an estimate of 18 milliseconds per menu), but if you have large multilevel menus, and a lot of site visitors, then the speed savings may bring a lot of benefits.
Just install and activate the plugin, there are no settings page.
A menu rendered normally takes around 0.02 seconds; activating this plugin reduces this step to 0.002 seconds.
Features
- Shaves off 18ms per menu
- Uses the Transient API
- Lightweight
- Cleanly coded plugin
How Does it Work
It's all about the Transient API. When a menu is rendered in the front end, the rendered menu is saved as a transient for caching. Future menu renderings use this cached copy afterwards. When the menu is updated, or when menu locations are changed, the transient is forcibly expired to make way for the updated menu.
This Is Also a Tutorial
Transients are cool. If you're not familiar with them then we documented the code well so that you can check it out.
There should be a companion tutorial about Transients soon.
