An interesting alternative that I've been using lately is colinux
(http://colinux.sf.net).  It lets you run linux in windows and compared to
vmware, I find it remarkably faster and when it is idle less resource
intensive.  I have vmware but if I'm only going to use a console based
program, colinux seems to outperform it.

Note that it may simply be interactive processes that run better because it
has a simpler interface and does not try to emulate the display hardware.
(Therefore no X unless you use vmware)  It seems though that there is less
overhead and if that's the case, then everything should run faster.

Also note that getting it installed is a little more work than vmware.  If
you're running it on a workstation that you use for normal day-to-day tasks
though I think you'll like it because you can detach the terminal and let it
run in the background.  When I do that I often forget it is running because
it produces such a low load on the system.  If you are going to give it a
try, the one trick I used to get things going was to download the newest
beta of winpcap and then the networking came up easily.  Everything else was
a piece of cake.
