Subject: [dpdk-dev] KNI performance is not what is claimed
Date: Thu, 20 Sep 2018 11:10:55 -0700 [thread overview]
Message-ID: <20180920111055.54d32242@xeon-e3> (raw)
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/sec 1.3 Gbit/sec
TAP 4.9 4.7
Virtio 5.6 8.6
Perhaps for 18.11 we should change documentation to remove language claiming
better performance with KNI, and then plan for future deprecation?
