Meh. 3.5meg/second from the winbox to the NAS (Infrant NV+), so no
change. It's a 2GHz c2D with 3gig RAM, Broadcom gigabit that pushes
50meg/second in other conditions (and maybe faster - that's hard drive
Pulling from the NAS is quicker - 6meg/second. Meh again.
The Apples and the Linux box get 20-40meg/second to the NAS. I'm
guessing it's some sort of dissent between the Linux that runs the NAS
and Cygwin's sockets.
I don't have a second Windows box to try like-to-like transfers.
