Ubuntu Servers :: SAMBA Is Slow On Newer Machine?

It takes 45min to transfer 10MB from my laptop to my replacement server. It takes 1minute to transfer the same 10MB from my laptop to the old server.

All connections are equal. Both servers are plugged to the same router.

Details: I have decided to migrate away from my Proliant 1600 to a slightly newer less complex piece of hardware.

Both machines are LAMP installs. Both are setup to be maintained headless 99% of the time and gnome is launched from the command line only when it is needed.

The older machine has more things running on it than the replacement. The replacement has nothing running that the older machine does not have.

Old box runs Ubuntu 6.06 but was fully updated a month ago. Replacement box runs Ubuntu 10.10 and was fully updated just last night.

smb.conf was the same on both boxes other than the share locations. Reading trying to fix it myself, I did put some known speedup lines into the new box's smb.conf, but it did not make a noticeable difference.

Hardware:
Old box,
Proliant 1600 = 1998 small server tech. (weighs 50lbs w/o drives)
single 500mhz xeon (upgradable to 2 600mhz, though they are hard to find reasonably priced)
1GB SDRAM with ECC

[Code].....

It does not matter what share/drive/partition I transfer to on either machine. The result is always the same.

On the newer computer CPU usage rarely goes over 50% and it has not had to go into swap at all yet.
