I have been using MathJax since before it was called MathJax (it used to be jsMath), and I've never found any synchronous rendering option to speed it up. You can minimize the page updates by not showing anything until mathjax is done, but that is disturbing to users (who either see nothing for an unknown amount of time, or see raw latex formulas), and it's frankly not much faster in my testing. If there really is such a MathJax option to synchronously render faster, then this page [1] should in fairness mention it.
