Your new version is still copying the entire file into mem. What you should try is changing your current approach:

undef $/;
my $bigfile = <$fh>;

# Do some processing on $bigfile

[download]
to something like this 
while (my $line = <$fh>) {
    # Do some processing on $line
}

[download]

Cheers,
