Syntax highlighter is too slow

[alerque]

This highlighter is too slow. Enabling it adds more that 5 seconds to open time for some of my Markdown files (e.g. 547K) over the builtin Markdown syntax.

Note I've reviewed e43c591 and reverted that change, and there is no measurable difference.

I have one large markdown file such that not only opening is slow, editing is painfully laggy. Is there a way to disable this plugin when I am editing on certain files?

:set ft=plain

(or markdown or something else you have a file type for you want to use other than pandoc).
