Hi All,
Since we announced CloudNetEngine virtual switch technical preview, we received
quite a few very good suggestions/feedbacks from evaluation customers, thank
you all!
Today we release CloudNetEngine vSwitch technical preview update 1, which
includes a number of performance improvements over last few weeks. Here we also
share more performance comparisons on Native kernel OVS, OVS-DPDK, and CNE
vSwitch technical preview update 1. The methodology for the comparison is also
commonly used by virtualization vendors, i.e. end to end TCP throughput/CPU
usage, and TCP_RR transaction throughput.
A few key observations:
- OVS-DPDK is not designed to optimize for intra VMs communication, its tcp
throughput is even worse than Native kernel OVS.
- OVS-DPDK only wins at TCP_RR, and this is reasonable as it always keep a CPU
core 100% busy.
- CNE vSwitch wins on almost all metrics (except OVS_DPDK's TCP_RR), and its
TCP throughput/CPU efficiency is around 3X against Native kernel OVS while also
provides better TCP_RR throughput than Native kernel OVS.

If you want to try CNE vSwitch technical preview update 1, please don't
hesitate to send a evaluation request to [email protected].
