I got rid of XP64... Logitech's support for their keyboards and mice on it isn't good enough for me so I'm back to XP32.  I've either messed something up or 32 bit XP handles multiple networks differently than the 64 bit did.
32 bit:  incoming over ethernet, outgoing over firewire.  I was copying files to the machine that had this taskman running.

64 bit: I expected the above taskman to look more like this one here - doing the same thing basically but both incoming and outgoing data for the transfer are on 1 connection.  The bump in the LAN graph is from going to a webpage with a ton of images on it.  I see that I still have .23% useage on the LAN in this shot but it didn't look like the one above before I started loading the web page.

64 bit: copying files to this machine from 2 other machines, 1 via ethernet and 1 via firewire.

Odd?  I can force it so that all the traffic is contained to the firewire connection by disabling the ethernet connection and it stays that way even if I re-enable the ethernet connection and continue to copy other files.  It's entirely possible I missed something somewhere - I'm no expert :)

I'll get on that test shortly.
