Yes there is - unfortunately we can't tell you, or it wouldn't be a
secret, would it? :)

Seriously, reading through the archives of this list should reveal that
the issue of choosing an optimal cache size is discussed regularly.
Usually, the concensus is that you should have enough room to store
between 5 and 15 days of traffic, regardless of how many users you have.

These actually look pretty good to me. Has anyone else been feeling that
the web is becoming less cacheable this year?
