Sounds like you are messing with $ signs in a manner that makes AUCTeX
think most of your document is math.

$\begin{align}$, by the way, is completely nonsensical.  I very much
doubt you'll get anything like that processed by LaTeX.

I suggest that you use

M-x TeX-submit-bug-report RET

for reporting your problem and include an example file showing the
problems.

The amount of font locking can be configured unless I am mistaken (I
don't use font locking myself).

However, if there is a significant performance impact, this points to
a problem that should get fixed, so a report with an example would be
welcome.
