Gigabit throughput tests?

What's a simple way to test a LAN for throughput after upgrading to gigabit?
(Cat5e cables, switch, patch panel, and patch cables will all be upgraded.)

Is there a utility to use for this purpose? Or some feature built-into the OS
to watch while transferring a large file?

LAN consists mostly of systems using WInXP and Mac OS X.

Thanks,

Is there some reason you're asking a question about wiring in a
wireless newsgroup? Not a problem, but I'm curious as to your logic.

I klike IPerf. Versions available for most OS's:
<http://dast.nlanr.net/Projects/Iperf/>
<http://dast.nlanr.net/Projects/Iperf/iperfdocs_1.7.0.html>
Setup a known good machine running Iperf as a server. Run:
iperf -s
On the various clients, run:
iperf -c ip_address_of_server
There are lots of other options to play with. Run the test in both
directions with:
iperf -r -c ip_address_of_server
as creative wiring sometimes causes traffic to work well in one
direction, but not the other.

As for watching large files go past, I kinda like to watch the
flashing lights on the switch. They're kinda hypnotic and counteract
the effects of coffee and running wires all night. If you want
detail, setup a sniffer computer, arrange a monitor port or use an
ethernet tap (or hub), and use Ethereal or WireShark, with a filter,
to monitor the traffic.
