I suspect the difference is your disk subsystem. IDE disks (in your laptop
I assume) quite often (almost always!!) ignore fsync calls and return as
soon as the data gets to the disk cache, not the physical disk. SCSI disks
are almost always more correct, and wait until the data gets to the physical
disk before they return from an fsync call.
I hope this helps.

Hi all,
Do someone already had some problem with performances using a pentium
D (64 bits) and postgres 8.2.3 on a redhat enterprise update 2 ?
I did the install from sources and nothing change... I have a RAID 0
for data and 3Gb of RAM and my inserts rate is quite low, 8333 inserts/
sec (lower than on my laptop which is 10526 inserts/sec).
I suspect a problem with the CPU because using gkrellm, the use of 1
CPU is always quite low... Is it normal ?
Many thanks for your help,
Jo�l
