Hi all, I've just gotten into my new database server yesterday and I've started doing database setup and tuning. I'm on a Rackspace Linux server with two raid arrays. Both are ext3. One is a two disk RAID1 I plan on using for WAL and OS, the other is a four disk RAID10 I will use for the data. I read in Postgres 9.0 High Performance that one of the most important parameters I should tune is the device read-ahead. My question: Is that advice just for the database drive, or should I increase read ahead on the OS/WAL disk as well? I assume both. I should ask the same for noatime advice while I'm at it. Is it important to disable atime on the WAL as well as the data?
