Are you sure it wasn't that generator expressions can be faster than list comprehensions (if the memory savings are significant)? Or that a reduction function with a generator expression can be faster than a module-level explicit loop (due to the replacement of dict-based variable assignment with fast locals in the generator and C looping in the reduction function)? In general, as long as both are using fast locals and looping in Python, I would expect inline looping code to be faster than the equivalent generator (but often harder to maintain due to lack of reusability).
