Take home: every single method here is really, really fast. 24k calls per second is not slow. You'd have to make some fairly radical mistakes in your API before that would ever matter!

If parameter parsing is really a bottleneck in your application then you're probably making too many subroutine calls! Much better than trying to tune parameter setup is to simply write methods that do work over sets of data. So instead of something like: 

foreach my $data (@rows) {
    $processor->do_one(data => $data);
}

Add support for: 

$processor->do_all(rows => \@rows);

But the vast majority of applications out there are not CPU bound to begin with - they're I/O bound either talking to a network, the filesystem or a database. In any of those cases you'd be pretty unlikely to see parameter parsing show up on a profile - I use Params::Validate all the time and I've never seen it show up.
