I am seeing what I would consider slow imaging performance to a SATA
drive. It is showing up as /dev/sda so I cannot do the hdparm to improve
the speed.

To put an image on the server it takes about 5 min - pulling from the
server onto the desktop is 10 min - image is 1.4GB in size.

Any advise on speeding up SATA would be appreciated.

Also we are using GB Broadcom NIC - showing that it is running 100FD - can
I get it up to 1000 ?? Using 6.5SP1 default linux.2
