Crossover and gigabit = insanity

Part of the gigabit standard is the auto MDX/MDIX capability.  In
English, every port that's gigabit capable will interoperate with any
other 10/100/1000 port without the need for a crossover cable.  Just
plug it in and get 'er done.  This is why a laptop with a gigabit
Ethernet port is a wonderful thing.

But speaking of transfer speeds, the best I've achieved from my
(..but, it's UNIX!!!) MacBook Pro, though a $45 8-port gigabit switch
was a sustained 48 MB/sec transfer for a 3.5 GB file.  Well, sort of.
The setup was like this:

I had two quad core Linux servers that were being rebuilt.  I copied
the working 32-bit CentOS virtual machine from one of them to the
laptop.  After rebuilding I opened two xterms on the Mac and set up an
SCP of the same file to each of the two servers.  The thought was that
if I start the transfer to both servers at nearly the same instant,
only the lead (first) transfer will actually read off the laptop's
hard disk.  The second transfer (same file, other Linux server) can
use the data that's still buffered in RAM.  I entered the password;
everything was ready - just needed to hit Enter on each window.
Naturally I have X set up for focus follows mouse, so I hit Enter on
the first window, moved to the second and hit Enter again.  The
transfer was 24 MB/sec to each server and even including the
encryption the Mac's CPUs were only at about 20% load.  The cheap
gigabit switch didn't slow anything down - YMMV.
