Chris will review the results of these benchmarks with an eye to addressing the following questions:</p> <h1>How does performance vary across JVM vendors?</h1> <h1>How does performance vary across JVM versions?</h1> <h1>How does performance vary across operating systems?</h1> <h1>How does the performance of 1.4 features differ from their 1.5+ replacements?</h1> <h1>How true are commonly held assumptions about Java performance?</h1> <h1>Can we generate simple rules of thumb for high-performance Java SE programming?</h1> <p>There will also be a short discussion of the tradeoffs between micro- and macro-benchmarks. Because this is a work in progress, comments and observations about Project Bonneville's benchmarking methodology, or suggestions for future benchmarks, are especially welcome.</p> <p>Chris promises a LOLCAT-free presentation, though there may be a slide or two of his kids.</p> <hr> <p>Speaker: Chris Cowell-Shah</p> <p>Chris does quality assurance for Oracle's Java-based Rules engine. He has also worked as an IT consultant for Accenture, and as a researcher for Accenture's Palo Alto research and development lab. He studied computer science and philosophy, and is always on the lookout for points of intersection between the two. <a href="http://www.cowell-shah.com/">http://www.cowell-shah.com/</a></p> <hr> <p>PJUG meetings start with some time to eat and socialize (pizza and beverages are provided), followed by the featured speaker, then Q&A, discussion, sometimes a drawing to give away swag. :)</p> <p>Though we like knowing how many people to expect, you don't <em>have</em> to RSVP, on Upcoming or otherwise. Go ahead and just show up!</p> <p>Many people also go for a drink and further discussion following the meeting, at a location determined ad hoc (lately, the Market Street Pub at 10th and Market: <a href="http://mcmenamins.com/index.php?loc=24">http://mcmenamins.com/index.php?loc=24</a> ).</p> <p><a href="http://twitter.com/pjug">http://twitter.com/pjug</a> <a href="http://pjug.org/">http://pjug.org/</a> (join our mailing list, linked from the website!)</p> </div> <h3>Links</h3> <ul> <li><a class="url u-url" href="http://pjug.org/">Website</a></li> </ul> </div>
