How long did it take the installer to create the file lists?

But running tex from the live DVD might be slower than if they were
ordered for that purpose.

http://www.tina-vision.net/tina-knoppix/remastering.html explains how to
use the -sort option of mkisofs to order files.  If one was to apply this to
a live DVD, however, I'd suggest sorting for optimal performance on typical
latex tasks rather than to make installs go faster.
