+Another option: ``pmd-cyclecount``, gives the user the opportunity to measure
+the number of cycles per operation for the 3 phases: setup, enqueue_burst and
+dequeue_burst, for both compression and decompression. An optional delay can be
+inserted between enqueue and dequeue so no cycles are wasted in retries while
+waiting for a hardware device to finish. Although artificial, this allows
+to measure the minimum offload cost which could be achieved in a perfectly
+tuned system. Comparing the results of the two tests gives information about
+the trade-off between throughput and cycle-count.
