Thanks for confirming that you also experience the slow-down.

I think that the only way to remedy this is to modify the
'org-src-font-lock-fontify-block' function in org-src.el to allow
just-in-time fontification, (rather than the current complete
re-fontification of the whole code block upon any changes).

Does anyone know of a list of 'nice-to-have' features that this could be
added to to allow possible development sometime in the future? 
(Unfortunately I am new to eLisp, and so making such changes is currently
beyond my capabilities.)
