Underground Notes from O'Reilly's OSCon

Some say Sun is as cool as OSCon (if not cooler) because, among most companies that support OSCon, only Sun can produce truly underground notes on OSCon.

David Van Couvering reviews Mike Olson's comments about his keynote at OSCon and pontificates about whether the value of Open Source could be limited to the collaboration it fosters. David aptly notes that

Open source and an open community gives you the assurance that the technology you are depending on is not going to be discontinued or put into "maintenance mode," it won't be acquired by someone who you would rather not do business with, and it won't be used as leverage against you to extract money or modify your behavior.

By way of further review, David contrasts MySQL as an Open Source project to PostgreSQL as an Open Source project.

In a separate underground note from OSCon, Barton George has posted his interview with Free Software Foundation lawyer Eben Moglen.

And There's PostgreSQL

To Find Things on Java DB

PostgreSQL for Enterprise Java

Anyone who has ever done any J2EE programming or managed or followed a project involving Java for the enterprise must have heard about the SpecJ standards.

In the first week of July 2007, Sun announced a very attractive SpecJ2004 result for an all open-source Sun stack, including PostgreSQL on Solaris on Niagara.

Josh Berkus and Jignesh Shah have already written about the recent SpecJ benchmark results. 

The highlights are already given by Josh and Jignesh's blogs: Josh notes the importance of the results in proving the suitability of the Niagara architecture for DB applications and the importance of this result as a proof of SMP scalability. He also notes the significant price difference between Sun and the competition and looks forward to even better SMP performance by PostgreSQL on Solaris. Jignesh gives some details regarding the DB tuning strategy used. If you want more of the tuning strategy details, you should probably leave him a comment.

Here's a summary of other highlights based on other sources:

• This is the second all open source SPECjAppServer2004 benchmark result and Sun is the only vendor to publish all open source results.
• It demonstrates Sun's commitment to use open source software at all levels of the stack -- including open source databases -- and to bring these price/performance benefits to users.
• An all-Sun, all open source stack comprised of PostgreSQL on Solaris (built off OpenSolaris) on T2000s (with OpenSPARC) with Glassfish gave 89% the performance at 34% the cost of a comparable HP benchmark with proprietary database, application server, and hardware. (Tom Daly provides further details regarding price-performance results.)
  

If you do not know about SpecJ 2004, refer to spec.org. In summary, SPECjAppServer2004 heavily exercises all parts of the underlying infrastructure that make up the application environment, including hardware, JVM software, database software, JDBC drivers, and the system network. The primary metric of the SPECjAppServer2004 benchmark is jAppServer Operations Per Second ("SPECjAppServer2004 JOPS") in either @Standard or @Distributed mode.

Look, also, at Tom Daly's blog for more information on these performance benchmarks and more.
