Tried this using projects/python/branches/release30-maint and using the patch that was just attached. With a 66MB input file, here are the results of this code fragment: for line in open("BIGFILE): pass Python 2.6: 0.67s Python 3.0: 32.687s (48 times slower) This is running on a MacBook with a warm disk cache. For what it's worth, I didn't see any improvement with that patch.
