I am curious what technique you used to determine memory
usage on your NT5 machine while "forked" processes were
actively running. Would you mind sharing your methodolgy?

Your comments suggest you do not have a memory usage
problem but rather a limitation within perl core
not allowing sufficient memory usage.

KDE is an adjunct software. Still, Linux is not as graphics
rich, audio rich nor has as many background processes running
after boot.

Redhat Personal has become vaporware mostly because of so many
difficulties writing support into core for drivers needed to
run various audiovisual devices wanted by common users.

Linux simply does not support what a majority of consumers
want; games, graphics, music and all that. This is not a
point of critique because Linux is not intended to be
competitive with Win machines. Linux and Windows simply
cannot be compared as they serve very different functions.

That is correct. Same code but different processes invoked.
You cannot make a valid comparison between Win32 forking
and Linux forking. Those are simply not the same.
 
I am very curious what methodology you used to check your
NT5 memory usage during your forking processes. Please do
share your code for this. Questions about memory monitoring
appear here on a regular basis. Your sharing of your code
to monitor NT5 memory during program execution would be
a benefit for many readers.
