Hmm, I followed that link but the only part of that discussion that
seems relevant is your comment saying:

  I've found elisp-fontify-semantically can be slow when font-lock is
  called a lot; e.g., when one uses the excellent indent-bars package.

If that's the part you were referring to, could you create a bug report
with some more details (e.g. a recipe for reproducing the slowdown)?


Thanks,

Eshel
