seemed like zipping the eggs made them slower to load, not faster.)
It's totally true. unzipped is faster because decompression adds
another processing layer which consumes more time than doing the
dma transfer of the extra bytes.
For those still using Z-80s or other 8-bit processors along with
C or assembler this isn't the case, but it will be true for any 32-
bit and above architecture running an elephant interpretor like
python.
I think P.J. Eby is right, we need to test it before analising the
results we don't have. Anyway even with a minor decrease in
performance using unzipped eggs makes things easier.
