If texvc is the underlying program that generates pngs at servers, it
fails. (eg:
http://bug-attachment.wikimedia.org/attachment.cgi?id=12248, error:
Parsing failed (lexing error)).

@Martin thanks for your comments and the link to the demo!
Just one slight correction regarding MathJax. Converting & typesetting of
TeX and MathML are basically identical in speed. But you're right that
MathJax's SVG output is often faster than HTML (up to 25%).
Can somebody comment on the state of texvc? That seems to be an important
question.

some mussing,
Why the exact size is needed? can't the formula be put inside a box
big enough, so 90% of the time the browser don't have to re-layout all
the page?.
Its other re-layour happening here? maybe the MathJax build the
formula incrementally and the browser try to render every iteration?
If that where the case, then It would be solvable with visibility:
none; <slow render magic happends here> visibility: normal;
What DOM is required? all of it? .cloneNode is very fast at cloning
DOM trees. Code can operate over a clone, then copy the result. If
the code is not attached to the page, maybe nothing will be rendered
until you .cloneNode back your new tree.
.cloneNode is faster than WeepingAngels :D

Ok this is getting off-topic -- sorry -- but glad you like it :)
Unfortunately, webworker isn't an option, we need the DOM. Using the PNG
for size is an nice idea, but only saves one measurement, all others
occur
within the equation. IIRC, the basic problem is that browser are not
reliable enough when it comes to em to pixel conversion; the only way to
get those correctly is to layout&measure -- recursively, of course,
building the equation bottom up. But you should talk to our devs if you
need more information on MathJax internals.

@Oscar that's the idea of bug
48036<https://bugzilla.wikimedia.org/show_bug.cgi?id=48036> To
test the user experience try this
bookmarklet<https://gist.github.com/pkra/5500316>
:-O
This is pretty. And if it still affect the browser (small freezes wen
the user is scrolling) maybe the javascript can be moved to a iframe
or a "web worker", so it don't run on the main javascript thread.
About re-layouts, can't smart use of "min-width min-height" avoid
that? you already have the size of the png as reference.
