Yes, my benchmark was cPickle vs. marshal. If you look at the extra
benefits that pickle offers over marshal (providing custom hooks,
handling recursive data structures, handling user-defined objects, etc.)
it's clear that marshal pretty much *has* to be faster, provided that
both implementations are high quality.
