When it takes the LTSP system about 35 seconds to boot up, I consider
a few seconds of time savings in reading the Etherboot file to be
significant.  Admittedly, I've never timed the difference between a boot
floppy and a boot CD, but I just recently started using CDs and I
perceive it to be significantly faster (a few seconds, I'd say).  

On the machines I've tested, the CD barely even spins up.  Maybe that's
specific to my particular cd drives, or maybe it's because the Etherboot
image is so small--it's read before the cd spins up to full speed?

I guess I'm gonna have to get out my stopwatch today...
