[dpdk-users] MEMPOOL contentions

In my setup, I created one mempool which is shared with 5 rings.
So, I want to know statistics of contentions between 5 rings like taking
time to get one mbuf.
In the manual, there are some options like CONFIG_RTE_LIBRTE_MEMPOOL_DEBUG.
However, I don't know how to use it.

Is there any reference?

Intuitively, as the number of rings are increase, I think the contention
happened frequently.
So, to avoid this, is increasing CONFIG_RTE_MEMPOOL_CACHE_MAX_SIZE one
