    Description

      The statistics provided by the segment cache are off due to the fact it serves as 2nd level cache: as it doesn't see all the hits in the 1st level cache (SegmentId.getSegment()), it reports a hit/miss rate that is to low.

      We should look into how we could expose better statistics wrt. caching of segments. Possible consolidated over 1st and 2nd level caches.
