It depends very much on what you're doing (and how you're doing it <wink>).

That's for sure.  Over the past week, several wrestled (behind the scenes)
with the relatively poor speed of f.readline() in Python (as compared to
"<f>" in scalar context in Perl).  Turns out that the single biggest
contributor to the difference is that Python reads in a threadsafe way while
Perl doesn't:  Python spends over half its time in system stream
locking/unlocking routines called by threadsafe system getc() (and friends).
Now that we know that, we were able to make large improvements (which will
be in Python 2.1) -- but it will never be as fast as thread-unsafe input.
