It looks like your previous timings, viz.

were better, at least as far as vertical-motion was concerned.  What
happened that caused almost twofold degradation in speed of
shr-vertical-motion?  And why does a single call to vertical-motion
take ~0.2 msec, while a single call to shr-vertical-motion takes 1.7
msec, more than 8 times more?

I don't see "Extant Carnivora species [Show]", I see "Extant Carnivora
species" with "Carnivora" a link to
http://en.wikipedia.org/wiki/Carnivora.  Is that what you meant?  (In
what browser do you see what you described?  I tried eww and Forefox,
and both show what I described.)

Anyway, which part of http://en.wikipedia.org/wiki/Carnivora is the
torture part? the "Phylogenetic tree" part?
