Just try it for your own.
Use the Benchmark module from CPAN.
But never forget,
speed is not so important.
(Otherwise you would have used C)
Readability comes first.
And then of course
it's important to avoid useless statements like
my $file;
which does really nothing more as a declaration.
That's why I would prefer:

> foreach my $file (@gzipped) { #do something else ; }
