Not better performance solution:
use strict;
use Benchmark;
my @convert;
for(0..10000){
$convert[$_] = '0' x (4 - length$_) . $_
}
my ($val1,$val2) = (int rand(10000),int rand(10000));
timethese 2_000_000 => {
array => sub {
@convert[$val1,$val2]
},
nobull => sub {
$val1 * 10000 + $val2
}
}
#where connectm can be
#sub connectm {
# my ($val1,$val2) = @_;
# @convert[$val1,$val2]
#}
__END__
Benchmark: timing 2000000 iterations of array, nobull...
array: 2 wallclock secs ( 0.78 usr + 0.00 sys = 0.78 CPU) @ 25
+57544.76/s (n=2000000)
nobull: 1 wallclock secs ( 0.52 usr + 0.00 sys = 0.52 CPU) @ 38
+83495.15/s (n=2000000)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
