if you wanted to actually take advantage of the crypto acceleration
capabilities of the processor your software would need to be specially written
to make the necessary calls to the CPU. Thankfully Sun and Oracle thought ahead
and wired these capabilities right into the JVM's crypto bits (also/formerly
known as JCE). So if you run the Sun JVM on Solaris you've got access to the
Sparc crypto acceleration for free! There's all sorts of great information out
there about these features. A good place to start is this article on the Sun Performance and Best Practices
blog. That post also points you to a couple of really great PDFs on Oracle
technet that discuss Weblogic on the T Series and SOA and OWSM on T Series.
A really good reason why using Sun Processors with the SUN/Oracle JVM makes perfect sense.
