Hi guys,
Just want to share these pgbench results done by DragonFlyBSD, and would
like some input on why these numbers look so bad and what can be done to
improve (ie. kernel tunables etc) the performance.

Just want to share these pgbench results done by DragonFlyBSD, and would
like some input on why these numbers look so bad and what can be done to
improve (ie. kernel tunables etc) the performance.
