I checked:

|  Original value was nil

I didn't have a chance to dig back into this but now I see other people are 
reporting slowness and I hope this helps.

I recompiled Emacs and Org last night and closed all my buffers except for two 
medium-sized ones, neither with any LaTeX in them.  I restarted and spent a 
minute or two with one buffer, closing and expanding headings, and just moving 
around without typing, and it quickly slowed down.  When I did do a bit of 
typing it was very laggy (and will only get worse). The profiler said this:

       44032  66% - redisplay_internal (C function)
       42619  63%  - jit-lock-function
       42603  63%   - jit-lock-fontify-now
       42551  63%    - jit-lock--run-functions
       42547  63%     - run-hook-wrapped
       42543  63%      - #<compiled 0x1badbc188025c93f>
       42535  63%       - font-lock-fontify-region
       42531  63%        - font-lock-default-fontify-region
       41987  62%         - font-lock-fontify-keywords-region
       40255  60%          - org-do-latex-and-related
       40243  60%             re-search-forward
          12   0%             org-string-nw-p
        1224   1%          + org-activate-folds
         156   0%            re-search-forward
         ...       

I'm happy to try anything else ...
