Run a benchmark on the systems and compare disk performance ("bonnie" is

If it's a lot slower it is probably a misconfiguration and not that the
hardware is slower. So verify that the new machine doesn't try to lookup
names that doesn't exist or something like that (enabling nis in
nsswitch.conf but not having a NIS system).

tcpdump/ethereal can be used to see what is being sent on the network for 
the 6.2 and 7.3 machines.

An other common misconfiguration is having mixes of full and half duplex
on the network cards. Verify the network speeds with something not related
to smb (ftp or a "real" networking benchmark like netperf).
