I wouldn't go believing benchmarks, unless they are running well written
programs doing what you want them to do and running on your system under
the conditions you want to run them. I'm sure it's not that difficult
to come up with a set of benchmarks demonstrating how much faster Perl
is than awk. Do you need that speed anyway?
I would suggest using awk if you need your input record separator to be
a regular expression. Take a look at $/ in perlvar.
I would also suggest using awk if you know it, you're happy using it and
it does what you want well enough for your purposes.
