Hi ,
We are using 'rte_mempool_create' for allocation of flow memory. This has
been there for a while. We just migrated to dpdk-18.11 from dpdk-17.05. Now
here is problem statement

Problem statement :
In new dpdk ( 18.11 ), the 'rte_mempool_create' take approximately ~4.4 sec
for allocation compared to older dpdk (17.05). We have som 8-9 mempools for
our entire product. We do upfront allocation for all of them ( i.e. when
dpdk application is coming up). Our application is run to completion model.

Questions:-
i)  is that acceptable / has anybody seen such a thing ?
ii) What has changed between two dpdk versions ( 18.11 v/s 17.05 ) from
memory perspective ?

Any pointer are welcome.

Thanks & regards
Venu
