GlassFish v2, 64-bit and default VM
By alexismp on Aug 21, 2007
Here are a couple of things that change with GlassFish v2 which should trigger better out of the box performance:
• GlassFish v2 also supports Java 6. Performance benefits are almost immediate and free (no code change, no recompile or redeploy). The use of JSR 199 by the JSP compiler is one of the benefits. The SPECjAppServer number is another one.
