Since 2.x is not backward compatible and quite different from 1.3; "exactly the same" isn't particularly meaningful - If the code was exactly-the-same it wouldn't work at all with 2.x. > The only changes we made were ones > required to make the application run on Cake 2.1.1.

Any issues of this kind are going to be in your app code, or in some way setup/config related. The cause, whatever it is, should be blindingly obvious (a loop of some kind; constant cache-misses or <insert other observed inefficiency>) by looking at what your code is actually doing AD -- Our newest site for the community: CakePHP Video Tutorials http://tv.cakephp.org Check out the new CakePHP Questions site http://ask.cakephp.org and help others with their CakePHP related questions.
