Untested and terse, but 

my @elapse= (0);
my %total;
my %only;
 
sub sub
{
    push @elapse, 0;
    # ...
    my( $name, $time );
    $total{$name} += $time;
    $only{$name} += $time;
    $only{$name} -= pop @elapse;
    $elapse[-1] += $time;
}

(Code updated)

So, after you fix the bugs, $total{prepare} tells you how long you spent in prepare() including calls to other subroutines while $only{prepare} tells you how long you spent in prepare() excluding calls to other subroutines.

If you want to track wall-clock time (etc.), then you can figure out how to extend that.
