I still don't understand why you say it's fake? I see syntax
highlighter code, so it works.

Mine took about 1 second, whereas before it was so quick I couldn't
measure it. So 1 second on a 10MB more that good enough for me. And
yes, all code after the initial (* was highlighted as comments - one
color of text.

Nope, didn't experience anything like that here. The initial Ctrl+end
after I added (* made the CPU jump to +-75%, and then instantly down
to normal idle behaviour. Moving the cursor up or down made no
difference - cpu around 2-5% as normal and cursor movement was as fast
as any other application. PgUp and PgDn repeatedly made the cpu go to
about 20-30% but that is normal too.  Maybe your computer needs a
reboot. ;-)

Attached is the CPU History graph.
