  it's slow. I wrote up a test script in Perl, Python and Ruby to do a regex search of a large text file. I'd post the numbers, but it would be ugly to look at. :) Long story short, Ruby was slowest of the three with execution times three times longer than Perl or Python. By the way, Perl was the fastest, but you knew that already. :)

    Show us the code and give us an example of the text file. That, or show the profiler results and I'll show you where/how you can optimize it (if possible).

    You're right, though. Perl is slightly faster than Ruby in most cases. This has mostly to do with interpreter startup time, but I think the Perl Development team also has simply had more time to tweak the C code. This is the sort of thing that will improve over time.

    Patches welcome. :)

      Yes, that damned Perl Development team. They've done such a bloody good job of tweaking stuff already that I'm finding it very hard to get perl to go any faster. And the parrot folks are even worse - they're trying to get it fast as they design it, so that us retrofit tinkerers can't even squeeze any more out of it. :-(

        Note that there has been some interest in and work put into the integration of parrot and ruby (named cardinal in the ruby community). That would remove (nearly all) the speed and library differences between perl and ruby.
