It would be fairly easy to check this by repeating the comparisons with
fsync = off in postgresql.conf. A performance number that doesn't
change much would be a smoking gun ;-).
The native port hasn't had any performance testing done on it yet, and
I wouldn't be surprised to hear of a gotcha or two. Perhaps with the
recent schedule change there will be some time for performance tuning
before we go beta.
