Re: Cache Digests

More cache digest questions:

Here's the latest:

store digest: size: 63797 bytes
         entries: count: 168771 capacity: 102074 util: 165%
         deletion attempts: 0
         bits: per entry: 5 on: 251104 capacity: 510376 util: 49%
         bit-seq: count: 255297 avg.len: 2.00
         added: 86521 rejected: 15553 ( 15.24 %) del-ed: 0
         collisions: on add: 1.48 % on rej: 1.43 %

I see the guesses are getting better: 165%.

What values would you think are "normal" or to be expected for
the on add: ?

What's the rej for ? rejected ? and the deletion attempts ?
I thought that you only added to the cache digest and simply
rebuilt from scratch later ?

BTW, when you are building the digest do you simply add every
single item in the cache ? or do you look at some of the meta-
data, e.g. expiry times - i.e. would you add something to the
digest if it was likely to expire very soon ? I guess "very
soon" would be related to often you rebuild the local cache
digest...
