In general, when you have a question like "which is faster", it's better
not to guess and just let the computer tell you.
Set up a test, one using NFS and one using LWP, Net::FTP or whatever,
and see how long it takes to copy 100 files. Or 1000. Or some large
files. Whatever you test, make sure your sample is a large number of
representative tests.
Look at the numbers, and see which is faster. :-)
See the Benchmark module for details. It's a standard part of the Perl
distribution, and describes ways to write Perl code to answer these
questions.
