Kinda my point is that when we've more load, we'd be using RAID-0 over 
RAID-5, or getting faster SCSI drives, or even turn fsync off if that's 
a bottleneck, because the different filesystems do not have that much 
performance difference[1] -- the filesystem is not a bottleneck. Just 
need to tweak most of them a bit, like noatime,data=writeback.

[1] That is, AFAIK, from our testing. Please, please correct me if I'm 
wrong: has anyone found that different filesystems produces wildly 
different performance for postgresql, FreeBSD's filesystems not included?
