I'm seeing slow disk transfers with Hardy (8.4.1) on a server. Windows
2003 server on older/slower hardware is performing better. I need to
improve the Ubuntu server performance! :)

Here are some examples of hdparm results on my Ubuntu Hardy server.
These are from a RAID-5 array on an LSI MegaRAID 320-2E SCSI controller
with 4x Seagate 15k rpm drives.

/dev/mapper/sdX_crypt:
 Timing cached reads:   1378 MB in  2.00 seconds = 688.89 MB/sec
 Timing buffered disk reads:  166 MB in  3.01 seconds =  55.12 MB/sec

/dev/mapper/sdX_crypt:
 Timing cached reads:   1368 MB in  2.00 seconds = 683.69 MB/sec
 Timing buffered disk reads:  170 MB in  3.02 seconds =  56.37 MB/sec

I have all the relevant info (dmesg, lspci, lsmod, hdparm, bonnie++
output, etc.) I will post it here if requested. Thanks.
