Don't expect to get good performance for more than 500mb total on a
NPE-G1.  Using a packet generator I couldn't even get 300Mb using
small (48 byte) packets.  If I upped the size to 1400 byte packets
then I could get 600Mb through.  These aren't real world of course.

Also, Cisco has a nice comparison on
http://www.cisco.com/warp/public/765/tools/quickreference/.  Check out
the router performance PDF where they say the G1 wll do 521Mb of
64byte packets (they must really have it tweaked to get that).

Bottom line, if you are gonna get more than 500Mb of bandwidth in the
next few years then you may as well get something bigger (7600 or
10000).
