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 (more often than not, Jax on 2nd).
