Hola Beto.
I have no idea where to look for that configuration or settings.
Yesterday I red about some drivers problems with SATA disk working togheter with IDE devices with DMA.
Mi server server is a Pentium VI 3.3 with hyper threading (enabled in BIOS), HP Proliant ML 110.
Then I entered to the BIOS and saw in IDE Configuration:
ATA/IDE Configuration [Enhanced]
Configure SATA as [IDE] => it has RAID option too
I have any idea how to continue!!! I don't know if this a SATA problem, a configuration problem or what else. I have installed several servers beggining with postgres 6.4 and I've neved had this kind of problems (always with IDE disks). I think this is a problem with SATA disk i/o, but I don't see how to measure that (I have already set postgresql.conf).
Regards
Agustin

Hola Agustin :)
otro argentino en el extranjero x aca ;)
anyway, back to English ;)
a long shot but...
check if you have any limits set on the host for CPU usage... you may be
limited to x number of secs / % by the OS scheduler. When you query your CPU,
it will say u are only using 5% or so...
chau,
Beto
