Here's the results of 'time java -version' on my MacBook Pro. I've also included the info about my system.

You might try profiling...

time java -agentlib:hprof=cpu=times -version

java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-112)
Java HotSpot(TM) Client VM (build 1.5.0_06-64, mixed mode)
Dumping CPU usage by timing methods ... done.

Also try profiling using Shark. That will do both Java and machine instruction profiling so you can see if the time is being spent in Java or doing something complicated in native code.
