Portland Java User Group: Java Performance Testing with Project Bonneville – Oracle (Downtown Campus) This month's topic: Java Performance Testing with Project Bonneville Project Bonneville is Chris Cowell-Shah's evenings-and-weekends open source project for measuring the performance of certain core Java SE features. Chris will review the results of these benchmarks with an eye to addressing the following questions: How does performance vary across JVM vendors?How does performance vary across JVM versions?How does performance vary across operating systems?How does the performance of 1.4 features differ from their 1.5+ replacements?How true are commonly held assumptions about Java performance?Can we generate simple rules of thumb for high-performance Java SE programming?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. Chris promises a LOLCAT-free presentation, though there may be a slide or two of his kids. Speaker: Chris Cowell-Shah 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. http://www.cowell-shah.com/ 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. :) Though we like knowing how many people to expect, you don't have to RSVP, on Upcoming or otherwise. Go ahead and just show up! 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: http://mcmenamins.com/index.php?loc=24 ). http://twitter.com/pjug http://pjug.org/ (join our mailing list, linked from the website!) |
