It does look to be the most efficient as you suspected.
The really fastest version -- which is only applicable if you no longer need the original array and can modify it in place, which is often the case in my work -- is:
my $i = 0; $x[ $i ] -= $x[ ++$i ] while $i < $#x; --$#x;
But the saving comes from not allocating more memory; and all the algorithms would benefit from that.
