  • 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. :)
    • Perhaps it depends upon how you wrote the program? From what was presented at the presentation, Ruby tends to be about 3% slower than Perl (whatever that means). If your program is running three times longer, I suspect that it's somehow due to the structure of the program. (unless, of course, there's something really funky about Ruby regexen that I am unaware of).
