Actually the build is *very* fast. The lookup is only averagely so since
Dan's implementation does heaps of seeks which seems to blow most Unices
caching nicely.
I have an implementation which mmaps the cdb file, and make cdb lookups as
fast or faster than Berkeley db. Obviously if your squid box is very
short of memory this will change especially if you have a large db.

[obviously for long lived processes you need to check occasionally that
the cdb file hasn't been updated(replaced).]
