cacherouter

Authcache offers page caching for logged-in authenticated users. This allows Drupal to load pages in 1-2 milliseconds and take the load off the the database & processor. Please help test this module (the site I was creating this for got axed, but I continued development on this module). Feedback & patches are welcome. This module can be used for anonymous users (it's faster than Drupal core since the database won't be hit), supports the statistics module, and can cache blocks of user-customized content.

Many thanks to Steve Rude for his work on the Cache Router module, which Authcache uses as its caching system.

This is how it works:

Hello Drupal world!

I released beta1 of the 7.x branch of Cache Router over the holiday. The new release passes all Core Cache Tests for APC, File, Database, eAccelerator, and Memcache. XCache is currently broken, and I'm working to get that engine working again as well.

So, some people have been asking about memcache for Drupal 6 and my personal modules have been neglected, but meanwhile I decided to come up with something new.

Let me introduce you to Cache Router. http://drupal.org/project/cacherouter

From the project page:

"CacheRouter is a caching system for Drupal allowing you to assign individual cache tables to specific cache technology. CacheRouter also utilizes the page_fast_cache part of Drupal in order to reduce the amount of resources needed for serving pages to anonymous users."
