I wonder if KNI is claiming performance that was never measured on current CPU,
OS, DPDK.
With single stream and TCP testing on IXGBE (DPDK), I see lowest performance
with KNI.
Rx Tx
KNI 3.2 Gbit/sec1.3 Gbit/sec
TAP 4.9 4.7
I meet similar issue with KNI connected VM, but In my case I run 2 VM
guests based on KNI and measure network performance between them:
sesion:

Hi,
I am running DPDP KNI application on linux (3.18 kernel) VM (ESXi 5.5),
directly connected to another linux box to measure throughput using iperf
tool. Link speed: 1Gbps. Maximum throughput I get is 50% with 1470 Bytes.
With 512B pkt sizes, throughput drops to 282 Mbps.
Tried using KN

The past few days I've been trying to chase down why operations over KNI
are so bloody slow. To give you an idea how bad it is, we did a simple test
over an NFS mount:
# Mount over a non-KNI interface (eth0 on vanilla Ubuntu 14.04 LTS)
$ time $(ls -last -R /mnt/sfs2008 > /dev/null)
