I’m most interested in Sun machines, e.g. V210, running Solaris 9 or later; will the JVM be executing on multiple CPUs, or will it be limited to running on a single CPU?

It depends on the Java applications you are running.
If you’re using J2EE, then yes. If you’re using J2SE then it depends on how well those applications are coded to take advantage of multi-threading, and how many applications are running simultaneously. Here are a few references:http://www.sun.com/software/whitepapers/…http://java.sun.com/docs/hotspot/HotSpot…
Performance will depend on a lot of things, including the JVM configuration settings, the Java applications themselves, the underlying thread model use (not a problem with Solaris >=9), etc.
Sun has been working hard for over a decade ensuring that the JVM keeps pace with the latest multiprocessing hardware.
