OK, scratch the MySQL idea. The overhead of 190-315 queries BY FAR* exceeds the benefits gained in lookup times.
.... and that's on a clean install of WP running nothing but Kubrick.

The problem is that every "caching hook" results in an additional MySQL lookup (though second hits for the same request do NOT reach the db).

I don't think there's any room for extra performance here. I'm using Indexes, Memory-based tables, high-speed lookups (the pack option); but MySQL wasn't created to be a dictionary ;-)

I can provide the code if anyone cares to look at it; but it seems like a dead-end here.

* query overhead resulted in 4-5 times longer page-loads.

Sorry guys!
