No, they run different test algorithms written in a variety of languages.

And? I never refuted that. I also pointed out that programmer work
declines dramatically as well. So move your eyes over to the third column and
state what output there.

Agreed. Which is why I made the difference between system programming (C)
and application programming (Python).

Sometimes, not often. And again, these are algorithms and tests designed
to exaggerate differences.

Which is never what I said. On the other hand there have been
applications which were written in Python and compared to their C counterparts
weren't all that harsh on the CPU or memory. Bittorrent clients come to mind.

Yes, now like I said, move your eyes over to the third column and see what
the shootout shows. Some algorithms are 1/3rd the size of the C counterparts.
Put that in perspective. A 60,000 line project in C would be 20,000 lines
in Python. As I said, a factor or two more CPU/RAM usage (0.5% to 2.5%, 3mb
to 12Mb, for example) to obtain several magnitudes of savings on the code
You don't think these languages are up to the task. I do. You have the
shootout on your side. I've got practical applications on mine.
