Actually, I'm afraid that it would run slower and require more RAM.
Decompression via cloop wins any reading benchmark versus the CD-Rom
speed and laser head movement. Also, the cloop block layer caching is
very efficient and read-optimized, so there are no duplicate buffers
created as opposed to compression on the filesystem layer.

They are, but putting KNOPPIX uncompressed on a CD-Rom will slow things
down by factor 2 or so. You may want to try by cloop-compressing and
reading a standard 700MB iso image. Even if your CPU is slow, reading
with compression factor 3 is still faster than reading the same amount
of data uncompressed.
Besides, not everyone can burn DVD images.
You CAN unpack Knoppix into a Directory KNOPPIX on a DVD, if you like,
it should still run the same if you use the same bootfloppy image, but
