so...turn off the "thunking" feature while you are debugging.

That won't help when you're debugging the performance implications of thunking.

compare memory / callcounts / time spent with thunking turned on vs. off would give a good idea of it.

i can say for my side of things thunking is a super huge performance gain as it allows for quick gathering of expression intent and then the computation side on the other side of a cache.
