GlassFish startup time on Mac Pro 3GHz

I tested GlassFish startup times on my Mac Pro 3GHz and a MacBook Pro Core 2 Duo 2.33 GHz. Times exclude the 'asadmin' overhead and are from initialization of the PELaunch class to the end of the startup sequence in the PEMain class.

Mac Pro 3GHz:  6.3 seconds
MacBook Pro 2.33GHz:  8.3 seconds

These times are for an EE version ('maven configure-cluster'), and represent a full startup, not a quick startup which defers initialization of some components. Times include some optimizations that have not yet been committed to the cvs repository; add about 2 seconds for the current trunk.

The Mac Pro is a seriously fast machine for most tasks, and does not disappoint for GlassFish startup time. However, the largely single-threaded nature of the GlassFish startup process leaves about 70% of the available CPU power unused.
