Hi,

hmmm i don't understand which are the best values for shmmax and shmall.
I've googled around but every site says something different.

I've 2GB of RAM now and set it to:

kernel.shmmax=715827882
kernel.shmall=2097152

Is that value ok for 2GB of RAM?

I've set the shared_buffers in my postgresql.conf to 87381
(87381*8*1024 = ~715827882).

Can I use www.powerpostgresql.com as reference to set this
parameters? Or which site can i use?

Best regards,
Martin
