/**
	 * This is the difference in performance of writing/reading secure data vs.
	 * writing/reading non-secure data for a very small payload.  
	 * Basic seems to be 75% of secure's time. This is a slowdown of 133% 
	 * for echoing 'hello'.
	 * 
     * Basic....
     * total write time         = 1402 ms
     * total write/response time= 1433 ms
