I think it's a fine idea to write the program to C++. Yes, a C++ program doing the same logic as a perl program will be faster. But I agree there may be a bottleneck in the perl program that could be fixed.
Normally, I do a short task using bash. But once it gets to a certain level of complexity, I move to C. It runs faster, but that's not the main point. It's so much easier to maintain a complex program in C than a complex program in a scripting language. The same logic applies to perl, which is kind of infamous for somehow leading to undecipherable code. On the other hand, there are large applications written in perl.
Quote:
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.
For the most part, I disagree with this assertion. If there is a graphic front end, it is often tricky writing multi-platform code. But for processing a log file, the program should compile on any platform, assuming the programmer is competent.

dir::self
Dir::Self(3pm) User Contributed Perl Documentation Dir::Self(3pm)
NAME
Dir::Self - a __DIR__ constant for the directory your source file is in
SYNOPSIS
use Dir::Self;
use lib __DIR__ . "/lib";
my $conffile = __DIR__ . "/config";
DESCRIPTION
Perl has two pseudo-constants describing the current location in your source code, "__FILE__" and "__LINE__". This module adds "__DIR__",
which expands to the directory your source file is in, as an absolute pathname.
This is useful if your code wants to access files in the same directory, like helper modules or configuration data. This is a bit like
FindBin except it's not limited to the main program, i.e. you can also use it in modules. And it actually works.
As of version 0.10 each use of "__DIR__" recomputes the directory name; this ensures that files in different directories that share the
same package name get correct results. If you don't want this, "use Dir::Self qw(:static)" will create a true "__DIR__" constant in your
package that contains the directory name at the point of "use".
