Looks like BEA is taking notice of GlassFish. Bill Roth offered some counter-arguments to our "10% better performance than BEA WebLogic 9.x" comparison, which is both expected and an appropriate thing to do. Bill asked some open-ended questions which I addressed for the benefit of the BEA community. I also offered some clarification around some of the points that Bill made so the WebLogic community has a better understanding of the GlassFish community. Bill's a busy guy (moderated comments) and the blogosphere is a moving window of conversation. In fear of missing the that window, here is a copy of the comment I submitted to Bill's blog.
Update: Alexis has a view on subject as well.
Update: Thorleif chose GlassFish over WebLogic (2nd comment) for the very reasons stated below.
Update: Hmmm, Bill never published my original comment to his blog, only the courtesy FYI ...
Update: Bill's SPAM catcher got in the way (see comments). No worries Bill, my email filter occasionally junk-mails my own emails
Bill, GlassFish V2 and the Sun Java System Application Server 9.1 are essentially the same, with the latter applying the Sun brand, indemnification and support. Sun benchmarked the Sun Java System Application Server 9.1 instead of GlassFish V2 because SPEC rules require a supported product. I highly recommend that instead of asking open-ended questions, you engage the GlassFish community via the user forums or the mailing lists where these and future questions can be easily addressed. To be completely transparent, I've updated the GlassFish User FAQ with the differences (GUI installer, 3rd party JDBC drivers, HADB) between GlassFish and the Sun Java System Application Server. These are not "significant differences" in our view.
Regarding our JVM, we don't need to be "pressed", simply asked (refer to the previous comment on user forum and mailing list). Yes, there are performance improvements between Java SE 5 and Java SE 6. However, since neither BEA WebLogic 9 nor BEA WebLogic 10 support Java SE 6, WebLogic customers cannot benefit from these performance improvements. It is good to hear that BEA has improved WebLogic tuning since the last submission since that benefits the larger Java community. The GlassFish community has made significant performance improvements between GlassFish V1 and GlassFish V2. The GlassFish community continues to actively work to improve performance across the board in a variety of areas.
I'll concede that benchmarking is a game of leapfrog. The main point is that GlassFish is performance competitive and extremely feature/price competitive at $4,500 for 4 sockets, which is why Gartner, Forrester, and Current Analysis are taking notice.
