SailFin is closing on v2.0 which is aligned with GlassFish v2.1.1 (both scheduled for the end of October, see Roadmap) and the team has been highlighting new features in the release: • Prasad Announces HCF, provides an overview and a List of Fixes since SCF. • Shreedhar writes about the Support for SSR (SIP Session Replication). • Ramesh describes the Configuration Options, including DNS failover and Converged LB. • Prateek Announces a new AMIs for SailFin based on OpenSolaris.   (also see EC2 Blog and Full List of Sun's AMIs)

If you've ever had to deal with Java performance tuning, you probably know about a few supported and maybe unsupported JVM tuning flags. Jeanfrancois "Grizzly" Arcand has a set of options for you when it comes to the Grizzly configuration (most are actually startup VM properties).

Here are my top picks (all apply to GlassFish v2):
• HTTP compression
• Comet support
• snooping support (I just like logging options)
• Asynchronous Request Processing
• Resource Consumption Management

As always and similarly to the JVM tuning case, the problem with having many options to choose from is to have methodology and good reasons to try them out. With greater power comes greater responsibility.

On the topic of Grizzly, there's a short article on JavaLobby for its 1.6.1 recent release.
