Re: V2.3 & Cache Digest

There is one flaw in my calculation, see below.

Due to domain partitioning, my clients would ask a set of two parents for
any object, so the request break even point is down to 2 mio requests per
day. If domain partitioning would not apply, every four caches would be
queried for objects, and the break even is even further down at 1 mio
requests per day and client.

Make that 1 .. 2 mio requests per day.
