Profiling, to find bottlenecks.

I can only second that. About three weeks ago, I had a factor 30 (3000%!) speedup after some litte benchmarking with Devel::NYTProf and nytprofhtml. One of the first actions after removing some of my really stupid code⁽¹⁾was to get rid of XML::Twig and use XML::LibXML instead.

⁽¹⁾ Don't code when your brain is in power save mode: Traversing a large tree to find the root node at least once for every node (900.000 times per script run) doesn't make your code faster. Using the root node that is already stored in $self does. ;-)

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
