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? > > And where's that page to begin with? > > http://en.wikipedia.org/wiki/Ocelot > > The torture test part of the page isn't shown by default.

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?
