[wp-hackers] wp_cache function tutorials?

[Jeff Rose]

Just wondering if anyone has resources or tutorials for the various wp_cache
functions or information on those versus using transients etc?

For example, if my blog/site was going to allow people to search a song list
(custom table of 20,000+ items) - should I cache it and how? That's just an
example for size though.

I've read the codex, but it's a little thin on practical use.
