I couldn't have said it any better.

As an example.  I run a SOAP server with Tomcat Standalone which uses
HTTPS for the transport.  I recently switched to PureTLS using a JNI
plugin so that OpenSSL libs were used instead of java byte code for
SSL.  The boost in performance was amazing. 10x faster.
