Scott Oaks is the person among others in our great Java performance team behind the excellent and recent SPECjAppServer performance results for GlassFish ([1], [2]). Scott has put out a GlassFish Tuning Primer one-pager.

It covers both JVM (throughput collector is suggested as the default choice for large heaps) and application server tuning (acceptor and request-processing threads, JDBC driver statement caching, etc...) and should serve as a good appetizer for our "hundreds of pages of tuning guidelines in our docset".

Here are a couple of things that change with GlassFish v2 which should trigger better out of the box performance:

•  GlassFish v2 supports 64-bit and thus can have a VM with terabytes of heap (see Performance Tuning Guide).

•  The GlassFish v2 configuration no longer has an explicit -client switch for better startup time in development mode. This means that Ergonomics will kick in to determine which is best, client or server VM. Read more here.
