Hi Karl,
On Linux you can get the number of cores with
my $no_of_cores = system ('/usr/bin/nproc');
I also tested your approach to split the load onto each core. It was slower than McA suggegestion and the serial processing of files but faster than the original parallel processing.
real 0m0.531s, user 0m0.449s, sys 0m0.208s
But thanks for sharing your wisdom. I learnt a lot about making use of a multi core cpu and splitting workloads.

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).

are good places to start.
