Most perl scripts are portable to a wide selection of operating systems. A C++ program would have to be rebuilt to move it to a different machine architecture and might need to be rebuilt to move it to a different operating system even if they both run on the same hardware.
If you are a competent C++ programmer, you should be able to write a C++ program that will run faster than an interpretive language like perl to perform the same job. (However, that doesn't mean that writing the C++ code to get an improved level of performance over a perl script will necessarily be easy.)

par::filter::bytecode
PAR::Filter::Bytecode(3pm) User Contributed Perl Documentation PAR::Filter::Bytecode(3pm)
NAME
PAR::Filter::Bytecode - Bytecode filter
SYNOPSIS
PAR::Filter::Bytecode->apply($code); # transforms $code
DESCRIPTION
This filter is deprecated. The B::Bytecode code has been removed from the newest development series of perl and will not be included in
perl 5.10 any more. Please have a look at Steve Hay's PAR::Filter::Crypto module if you want to hide your sources.
This filter uses B::Bytecode to turn the script into comment-free, architecture-specific Perl bytecode, and uses ByteLoader to load back on
execution.
For pp users, please add an extra -M option, like this:
pp -f Bytecode -M ByteLoader
Otherwise, the implicit dependency on ByteLoader will not be detected.
CAVEATS
This backend exhibits all bugs listed in B::Bytecode, and then some.
Bytecode support is considered to be extremely fragile on Perl versions earlier than 5.8.1, and is still far from robust (as of this
writing).
Bytecode is not supported by perl 5.9 and later.
