* This applications is a simple test app used to test the performance of

* to measure the effect of changes to the spdk_histogram_data implementation.
*
* There are no command line parameters currently - it just tallies
* datapoints for 10 seconds in a default-sized histogram structure and
* then prints out the number of tallies performed.
