Why do you say RSS feeds have no content to cache? There is the title, date and then, well, the content, either in the description element or content:encoded. And even in cases where it's just a title and a date, it takes time to open the connection and download the file.

The benefit is: once cached, do not have to connect to server and download the Web page. When there are 30 pages, this is an issue.

I'm already parallelizing the retrieval. I'm using LWP::Parallel after finding little additional speed benefit from either POE or HTTP::GHTTP with P::ForkManager.

Thanks anyway.

• 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).
