    Khan Academy has developed a MathJax alternative, called KaTeX, which is apparently significantly faster. See a performance comparison here (note that the length of the bars represent operations per second, not seconds per operation as I first assumed). The LaTeX subset it supports is pretty limited at the moment, see here, but I think it’s worth keeping an eye on the project, as I think it would really cut down our page load time. Thanks to David Roberts for making me aware of this.

    Does KaTeX convert from MathML or only from its LaTeX subset? If it doesn’t convert from MathML then it is irrelevant for the nGroup webpages. And that’s the conversion that you’d need to look at, not conversion from its LaTeX subset. Moreover, I wonder how much of that performance gain is due to its limitations.

    So keep an eye on it, but a wary one.

    How on earth are they getting around the problem of requiring reflow? That seems like magic…

    This issue on GitHub makes it look like they don’t use/support MathML.

    EDIT: no, I got it wrong. That issue is asking whether they could render to MathML, and it doesn’t do that. Not sure how to find out except asking the devs.
