Re: Tuning PostgreSQL

Thanks, i'll look further into these mount setting.

I was just thinking, the server will have a (RAID) controller containing
128Mb of battery-backed cache memory. This would really speed up inserts to
the disk and would prevent data loss in case of a power-down also.

What would you guys think of not using RAID5 in that case, but just a really
fast 15.000 rpm SCSI-320 disk?

Kind regards,
Alexander.
