Обсуждение: Potential Problem with PostgeSQL performance on SuSE Linux 9.0

Folks,

While debugging a wireless card, I came across this interesting bit:
http://portal.suse.com/sdb/en/2003/10/pohletz_desktop_90.html

What it indicates is that by default SuSE 9.0 plays with the timeslice values
for the Linux kernel in order to provide a "smoother" user experience.   In
my experience, this can be very bad news for databases under heavy multi-user
load.

I would suggest that anyone installing a SuSE 9.0 PostgreSQL server remove the
Desktop pararmeter in the bootloader configuration.

Along similar lines - have generally obtained better server performance
(and stability) from most Linux distros after replacing their supplied
kernel with one from kernel.org .

regards
