On my 4-core i7 Macbook Pro: time ./startup_time.pl 0.016s time ./startup_time.py 0.295s Parsing a 20Mb log file with a regex: time ./parse_log.pl 0.683s time ./parse_log.py 1.534s For which metric are you claiming Perl is slower than Python?

Lets see the code? Regex has always been a Perl selling point, and you're just benchmarking the Python Regex library (written in C) against Perl's regex library. That's not a fantastic basis for a comparison.

    #!/usr/bin/env perl
    use 5.026;

    open my $fh, ') {
      chomp;
      say if /\b\w{15}\b/;
    }
    close $fh;

    #!/usr/bin/env python

    import re

    with open('logs1.txt', 'r') as fh:
        for line in fh:
            if re.search(r'\b\w{15}\b', line): print(line,   end='')

What do you mean by cheap? Also, perl is incredibly inefficient: it's even slower than Python. Also, how is Perl any less stable than other languages? Are you saying the language doesn't change much or that it doesn't crash?

- Efficient: from prototype to deployment, it's a matter of days. The choice of styles let people use paradigms they are familiar with, meaning they do things quickly. - Cheap: it does not cost much to hire someone to write perl. If they don't know how yet, the choice in style let them be efficient quickly. The code to be deployed is very lightweight, both in CPU and RAM usage. - Stable: no API break. No new module t…

This seems to be a common experience - people say it felt powerful and modern in the 90s, because it was . For those who started programming in the 00s and 10s it looks clunky and weird compared to the other options.

That doesn't add up because today's most popular languages - JS, Java, Python, PHP and Ruby - were also released in the 90s.

They last line of the article summarizes it well: > Perl 7 is v5.32 with different settings. Your code should work if it’s not a mess. Expect a user release within a year. Are there actually people that are still deploying new things in Perl? The only times I see it is for legacy stuff, and then only because the script is too much of a hassle to be rewritten.

Yep, I know of one company still actively using Perl for a large part of its infrastructure. It has its use cases.
