fxTeX vs KaTeX vs MathJax vs Temml

Run one library on its own: fxTeX · fxTeX Pro · KaTeX · MathJax · Temml · the source page they all render

Each library renders the same 57-equation page (content.html, 57 inline/display equations across algebra, calculus, trig, linear algebra, sets/logic, probability, and piecewise definitions) loaded fresh into an iframe per library. load = navigation start → library script ready. init = the library's own share of that: from its last script byte arriving to ready, so compile + evaluate + startup work, with the page's own fixed cost taken out. convert = the actual "scan the page and render every equation" call. total = load + convert, the number a real visitor would experience. All timings are the median across runs (min shown in parentheses). min.js is each library's own minified script size, fetched fresh each run (not a proxy for the *load* column above - that's cached-script parse/init cost; this is the one-time download a first-time visitor actually pays, which a same-machine benchmark can't time honestly - see the README). All four libraries are served from this folder (vendor/, refreshed with npm run fetch-libs), never from a CDN, so they share one origin, one server and one cache. version is read back from the page that actually ran, not from a manifest. Every completed run is kept in this browser's history below, so a library update shows as a change against the numbers its previous version produced.
