Marion,
Thank you for the feedback. This should give me enough to scratch out some
basic rules for our system.
Much appreciated!

It is more educated guess than reasoning and math.

Hello,
I am looking to understand the math and reasoning behind the 16K DPDK MBUFs per
socket allocation.
From: vpp/src/plugins/dkdp/device/dpdk.h
#define NB_MBUF (16<<10)
The following online documentation has a comment stating it is 32K per socket.
Above == 16K, and does not seem to align
I have tried to adjust the num-mbufs to a value higher than 42 and this
resulted in daemon crash about 1.3 minutes after starting it.
This is happening on
-vpp v18.04-rc0~218-g07510dd
-CentOS 7.4 - 4.15.0-1.el7.elrepo.x86_64
