The other point is that Perl is written in C/C++ too... If the Perl code spends most of its time using external modules, or just doing I/O, its performance may be quite comparable to a pure C++ program. If it spends most of its time doing complex data processing via perl statements, perhaps not so much.
So there's one easy benchmark for you. If this Perl program uses lots and lots of CPU power while running, it may benefit from optimization. If it doesn't, it's spending most of its time waiting for data to arrive or be sent... A C++ version wouldn't be able to wait much faster

Perl::Critic::Policy::ValuesAndExpressions::RestrictLongUsernContributed Perl DoPerl::Critic::Policy::ValuesAndExpressions::RestrictLongStrings(3)
NAME
Perl::Critic::Policy::ValuesAndExpressions::RestrictLongStrings - Stop mixing long strings with code.
AFFILIATION
This policy is part of Perl::Critic::More, a bleeding edge supplement to Perl::Critic.
DESCRIPTION
Long text strings in the middle of code is very distracting and wreaks havoc on code formatting. Consider putting long strings in external
data files, "__DATA__" sections, or in their own subroutines.
This policy complains if a long string is not the last line of a subroutine. "Long" is defined as 78 characters by default. This value
can be altered in your Perl::Critic configuration via the "max_length" property. For example, you may add the following to your
.perlcriticrc file:
[ValuesAndExpressions::RestrictLongStrings]
max_length = 50
