in reply to Fastest XML Parser ?

I maintain a series of benchmarks for various cases named Ways to Rome. The short answer is that the fastest parser is XML::LibXML.

In your case if XML::Simple is that slow, maybe that's because you are using it's default, pure Perl, parser which is really slow. Do you have XML::LibXML or XML::Parser installed? You might also need to set the $XML_SIMPLE_PREFERRED_PARSER (or $XML::Simple::PREFERRED_PARSER) to XML::Parser or XML::LibXML. See the Environment section in the docs of the module.

    FWIW: $PREFERRED_PARSER should be XML::LibXML::SAX; just "XML::LibXML" falls down hard. And it did speed it up (0.4 secs vs. >1 sec). But XML::Simple's docs need a bit more clarity on the subject, cuz I tore out significant chunks of hair trying to find the secret sauce. (Not to mention the agony of setting up LibXML on Windows and fussing w/ environment variables so XML::LibXML could find it..).
