.. note::
- To get statistics on the sample app using the command line interface as described in the next section,
- DPDK must be compiled defining *RTE_SCHED_COLLECT_STATS*, which can be done by changing the relevant
- entry in the ``config/rte_config.h`` file.
+ Number of grinders is currently set to 8.
+ This can be modified by specifying RTE_SCHED_PORT_N_GRINDERS=N
+ in CFLAGS, where N is number of grinders.
