LOL, disregard. I see this post is over 2 years old. :-P

No offense (I’m a BSD advocate), but I’d like to see some hard numbers to back up your claims. Specifically, the time for vaccumdb on each. Then a profiling of each “process” you’re performing with details on the application architecture.

Other people need details so they can generate a repeatable comparison.

I’d be curious to see the difference between these setups using a similar hardware raid.

Jaxxed:

There is no follow up article _yet_, but last week I made a quick test between these 2 boxes:

1) a modern dual xeon with raid-0 running debian sarge (kernel 2.6.8) and postgresql 7.4.7 (xfs noatime filesystem)
2) the old dual xeon i mentioned running freebsd 5.3-p10 in an old scsi drive (no striping) and postgresql 7.4.7 (ufs2+s)

I just loaded both machines with the same DB and then performed a “vaccumdb -faz” lots of times, the old box with freebsd was always faster. I didn’t run any more tests (yet).

it’s funny how much similar a flames war in spanish is to a flame war in english … anyways, outside of the ridiculous linux battle going on in the middle:

I too am curious as to what the major factors in the difference were. I am a FBSD enthusiast, but I would never have thought to advertise that kind of a difference.
If it was the RAID/FS combo I would be interested to know.

Is there a follow up article already
