Edit Question
Title
Body
I've been playing around with a timing decorator for my pylons app to provide on the fly timing info for specific functions. I've done this by creating a decorator & simply attaching it to any function in the controller I want timed. It's been pointed out however that decorators could add a fair amount of overhead to the call, and that they run 2-3x slower than an undecorated function. Firstly, I would expect that executing a decorated function would take a smite longer than an undecorated one, but I would expect that overhead to be in the thousandths of seconds & be negligible compared to a SQL insert call. The decorator itself does simple simple timing calculations using time.time() & some very simple aggregation. Do decorators add significant overhead to a system? I can't find anything to back that up.
