  GVC 4-port ADSL modem + router combo (10/100 megabits).  The newer
machine has a 100/1000 megabit nic, and the older one has 10/100.

  emerge (the Gentoo fetch and install command) uses wget.  The process
is automated.  I believe the numbers.  The Firefox tarball, 35 megabytes
worth, came down in approx 3 seconds.  I don't think the older machine's
hard drive can keep up that pace.  It seems to max out at around 3.5
megabytes.  However, 35 megs could queue up in ram, waiting to be written
to disc.  There's also a second or so of handshaking between files.  It
helps that the older machine (128 megs of ram) was only running sshd at
the time.  If the file was multi-gigabytes, it would easily fill up all
buffer space, and slow down to a more realistic speed.
