One difficulty I run into with a lot of these Intel accelerations... each one
is described as an atomic entity independent of all the other possible
accelerations. Nobody explains how to take all of them together to make a
complete high-speend low-latency packet processing solution from L1-L7.
It'd be nice to see an architecture level view of DPDK, along with the
accelerations one could / should apply at each level, so there's some kind of
checklist you can follow to be sure you used everything you should where you
should. Otherwise you'll miss some stuff and waste the features you paid for.
Also, how is DDIO different from the previous DCA accelerations?
Thanks,
Matthew.
