The webserver is a 1U and it actually performs better on the IO than the
database server even though the database server is running 6 disks versus 3.
The database server is a PE (Power Edge) 6600
Database Server IO:
[EMAIL PROTECTED] root]# /sbin/hdparm -tT /dev/sda
/dev/sda:
Timing buffer-cache reads: 1888 MB in 2.00 seconds = 944.00 MB/sec
Timing buffered disk reads: 32 MB in 3.06 seconds = 10.46 MB/sec
Second Database Server IO:
[EMAIL PROTECTED] root]# /sbin/hdparm -tT /dev/sda
/dev/sda:
Timing buffer-cache reads: 1816 MB in 2.00 seconds = 908.00 MB/sec
Timing buffered disk reads: 26 MB in 3.11 seconds = 8.36 MB/sec
[EMAIL PROTECTED] root]#
Which is just horrible.
Sincerely,

That's too bad, can you cite some model numbers? SCSI?
I would be interested too, given
