An earlier post referenced a bunch of Oracle performance pages. One of them,
http://www.ixora.com.au/notes/direct_io.htm indicates that on Linux 2.4 kernels one can use Direct I/O (if you DB supports it). Does Postgresql support the use of Direct I/O or Raw I/O? Base on another page http://www.ixora.com.au/tips/avoid_buffered_io.htm it would seem that not using one of these "wastes" alot of RAM. Just curious .... I am a couple of months away from production.
