Subject: Re: [dpdk-dev] [PATCH 0/8] add vhost TX offload support
Date: Mon, 26 Oct 2015 06:45:09 +0000	[thread overview]
Message-ID: <1ED644BD7E0A5F4091CF203DAFB8E4CC22BC311C@SHSMSX101.ccr.corp.intel.com> (raw)
In-Reply-To: <1445402801-27806-1-git-send-email-jijiang.liu@intel.com>

We have tested the following case on Intel 10G NIC using the patch set.

Test case Flow:
 Iperf app running on legacy virtio guest---->DPDK vhost-----> two physical ports loopback on a NIC ----> legacy vhost----->iperf app running on a legacy virtio guest.

After enabling the vhost TSO and checksum offload,  there is about 60% throughput performance improvement.

And we will continue to test the performance after the patch set is applied.
