Significantly slower than marked, but does more

[peterbe]

I used to use marked but now exploring marktex.
However, before I swapped I put some logging around how long it takes to render. E.g.

  let t0=performance.now()
  text = marktex(text)
  let t1=performance.now()
  console.warn('marktex', t1-t0);

I did this for both rendering engines. Ran lots and lots of markdown through them and the collected the times and analyzed each's average:

MARKED 0.146812227074
MARKTEX 1.331

I know I need the gfm features but I'm not entirely sure what options are the ones that slow down the most. Is it just that marktex does more?

I tried changing to marktex(text, {gfm: true, marktex: false}) instead and it's still much slower:

MARKED 0.0980534918276
MARKTEX 1.06930678466
