  I mentioned this on #perl6, but I think you missed it -- the high-performance user ("Ilya") may be doing bandwidth-intensive stuff as well -- it's important then to have efficient access to packed data streams.

  This becomes especially important when each data element requires very little computation, but there are a LOT of data elements to go through.

  Hmmm, perhaps this should be a new user type . . . .

    Lots of calculation and lots of data movement are closely related, but I don't know if they're the same or not. If you're moving so much data that the mere movement of it is a challenge from Perl, actually processing any of it substantially is probably a C-language issue (e.g. mpeg compression).

    Perhaps you could contribute an "Ilya Prime" sub-profile?

        "Ilya Double Prime" and "Treefrog" have a lot in common.... regards, treefog
