those following IRC might know what this is about. For the rest: I did
some performance testing of PostgreSQL on DF with HAMMER and UFS and
the attached document is the (preliminary) result of that.
Any comments/proposals are welcome. Especially if someone could
comment on the technical background (HAMMER internals) that support or
contradict my findings.

thanks for taking the time to run a solid benchmark run.  I think this shows clearly where HAMMER needs improvements.
