That is, at first glance it's much faster to do a million appends in pure Python than it is to let zip do them at C speed. I'm curious about what people get for this program on other platforms (pymalloc on or off may make a dramatic difference too -- or not, depending on how the platform malloc works).

OS/2 EMX (2.2.1 without pymalloc) justpush 0.59 justzip 8.85

OS/2 EMX (recent CVS with pymalloc) justpush 0.54 justzip 8.81

FreeBSD 4.4 (2.1.1 w/o pymalloc) justpush 89.72 justzip 110.41

FreeBSD 4.4 (recent CVS with pymalloc) justpush 19.21 justzip 46.32

The FreeBSD box is more mature hardware (P5-166). I'm surprised at the difference in the 2 sets of results on it. AFAIK, the compiler version and switches are identical for the two interpreters (the 2.1.1 is from the binary package on the FreeBSD 4.4 CDs).
