Probably, but not necessarily. It could be that because of differences in sys.path there's a difference in whether some basic libraries like pickle vs cpickle (to pick a really random example) are getting loaded. Not a diagnosis; just a possibility, maybe a remote one. If you're doing elapsed-time measurements, you might build a list of timestamps of intermediate steps, and then print that. > > I do note, however, that when I tried to incorporate the code into web2py, I > found a namespace clash (class Package appears elsewhere in the web2py > installation).
