You could hard code all that data, updating whenever you have the time, or with some simple Perl scripting magic, you could automate the whole process!

Pretty standard stuff, but if you're a programmer that's been double tasked with maintaining the systems you work on, this will be helpful. Even if you're not a system administrator, I highly recommend that you learn to compile Perl yourself on your own systems.

Definitely something that you should avoid if you're using the combo of Perl and Red Hat in a production setting. Apparently there's a patch in the pipeline that has yet to get into the Red Hat packages yet, and you can compile Perl yourself and bypass the problem all together. <br /><br /> <a href="http://clk.about.com/?zi=1/1hc&#038;zu=http://blog.vipul.net/2008/08/24/redhat-perl-what-a-tragedy/">Red Hat Perl performance problems</a><p style="background:#f5f3ef;border: 1px solid #d5d0bf;padding:.5em;"><a href="http://clk.about.com/?zi=1/1hc&zu=http://perl.about.com/b/2008/08/30/red-hat-perl-performance-problems.htm">Red Hat Perl performance problems</a> originally appeared on <a href="http://clk.about.com/?zi=1/1hc&zu=http://perl.about.com/">About.com Perl</a> on Saturday, August 30th, 2008 at 10:45:56.</p><p><a href="http://clk.about.com/?zi=1/1hc&zu=http://perl.about.com/b/2008/08/30/red-hat-perl-performance-problems.htm">Permalink</a> | <a href="http://clk.about.com/?zi=1/1hc&zu=http://perl.about.com/b/2008/08/30/red-hat-perl-performance-problems.htm#gB3">Comment</a> | <a href="http://perl.about.com/gi/pages/shareurl.htm?PG=http://perl.about.com/b/2008/08/30/red-hat-perl-performance-problems.htm&zItl=Red Hat Perl performance problems">Email this</a></p> http://perl.about.com/b/2008/08/30/red-hat-perl-performance-problems.htm Sat, 30 Aug 2008 10:45:56 +0000 2008-08-30T10:45:56Z http://perl.about.com/b/2008/08/23/why-i-stick-with-perl.htm Why do people keep using Perl when there are seemingly other 'up-and-coming' languages out there?
