Personally, if the application permitted it, I'd go for:

sub ords{ sprintf "%02x " x length($_[0]), unpack 'C*', $_[0]; }

In addition to being a bit quick, I find the shorter dumps using hex more useful.

If I was really after ultimate speed and the strings to be dumped were of some reasonable maximum length, then I might consider using:

{
    my $t = '%02x ' x 1000; 
    sub ords2{ 
        sprintf substr( $t, 0, length $_[0]*5 ), unpack 'C*', $_[0]; 
    }
}

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
