I'd gotten the impression that rendering was slower.
Thanks for confirming.
So it's cheaper to use "show changes" by
a factor of 20.
That much!
In fact, we've been considering suppressing the
"current version"
display from diff pages...
But until you do, I guess the point (i.e. which button a
conscientious bot or user should press first) is moot, since the
slow preview button takes 800 ms, and the fast diff button takes
40+800ms.
