Subject: [dpdk-dev] DPDK - VIRTIO performance problems
Date: Sun, 12 Oct 2014 12:37:37 +0000 [thread overview]
Message-ID: <CEFFBC011B3590479939EA0B9311D2152690DFF8@ILMB1.corp.radware.com> (raw)
Hi
I am checking performance DPDK VIRTIO mode running on KVM (Linux ubuntu 3.11.0-15-generic).
The maximum throughput I reached was 4Gbps and then I saw an interesting phenomena.
Every ~2min traffic stopped completely and then immediately came back. This happened in a periodic fashion.
I have never seen such thing in a pass-through mode, where I reached very much higher rates of course.
Can you please help in resolving this problem in VIRTIO ?
Thank you
Yan
