File::Find seems grossly inefficient for performing simple file tasks

[taint]

Greetings,
In an effort to figure out how to perform the equivalent of this shell script:

find ./iso/ -type f -cmin '+11' -uid web -exec rm '{}' \;

using Perl. I made use of one of the Perl utilities, find2perl. After reading it's syntax, I used what I understood to be the equivalent:

find2perl ./iso/ -iname '*.xz' -user web -ctime 1 -exec rm '{}' \;

-- with 2 exceptions;
1) I added -iname '*.xz'
2) I was unable to define time in minutes, as only -ctime is available, which == day(s).
I had expected a similarly short equivalent to be returned upon execution. But much to my surprise, I received the following:

#! /usr/local/bin/perl -w
    eval 'exec /usr/local/bin/perl -S $0 ${1+"$@"}'
        if 0; #$running_under_some_shell

use strict;
use File::Find ();

# Set the variable $File::Find::dont_use_nlink if you're using AFS,
# since AFS cheats.

# for the convenience of &wanted calls, including -eval statements:
use vars qw/*name *dir *prune/;
*name   = *File::Find::name;
*dir    = *File::Find::dir;
*prune  = *File::Find::prune;

sub wanted;


my (%uid, %user);
while (my ($name, $pw, $uid) = getpwent) {
    $uid{$name} = $uid{$uid} = $uid;
}


# Traverse desired filesystems
File::Find::find({wanted => \&wanted}, './iso/');
exit;


sub wanted {
    my ($dev,$ino,$mode,$nlink,$uid,$gid);

    (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
    /^.*\.xz\z/si &&
    ($uid == $uid{'web'}) &&
    (int(-C _) == 1) &&
    (unlink($_) || warn "$name: $!\n");
}

Is this right?!
I'm not going to pretend to be a Perl GURU -- far from it. But even after removing the comments, this seems to inefficient -- no?
Anyway, if this is really the best option to perform such a short task in a shell with Perl. It looks to me that "shelling out" within Perl is more efficient -- minus Taint, of course.

Thank you for any consideration in this matter.
