[osol-discuss] Performance of opensolaris

Hello,

The previous thread reminds me of one surprising fact I've been 
fundering over for some time.

Now I love opensolaris and I have SXCE 64bit installed on my home server 
(Quad Core E6600, Asus P5W-DH mobo, 8G ram PC6400, SATA disks in AHCI 
mode). Zfs of course.
My work machine is a 2 year old Dell laptop (Core 2, 1G ram), running 
WindowsXP.

I use postgresql quite a lot (though rather small databases), and I have 
a backup on the server.

The surprising fact is that the performance is still slightly better on 
my laptop than on the server. This has been true with postgresql 8.3 and 
now with postgresql 8.4 as well.
I find this quite surprising as both hardware and OS (64bit) seem to be 
a lot better on the server.
Furthermore, I had to tweak postgresql a bit to even get on the same 
level of performance than the default windows setup.

Is there any explanation you would think of ?

Bruno
