Have you tried running x-data-plane=off with vcpu = 8 and how does the
performance compare to x-data-plane=off with vcpu = 1?

-> Host : 256GB, CPUs : 31, Guest : 48GB, VCPUs : 8
Thanks.

Hello All.
Nowdays i measured io performance with Virtio-Blk-Data-Plane.
There was something strange in test.
When vcpu count is 1, io performance is increased in test
But vcpu count is over 2, io performance is decreased in test.
i used 3.10.9 stable kernel, qemu(1.4.2) & fio 2.1

Hello All.
Nowdays i measured io performance with Virtio-Blk-Data-Plane.
There was something strange in test.
When vcpu count is 1, io performance is increased in test
But vcpu count is over 2, io performance is decreased in test.
i used 3.10.9 stable kernel, qemu(1.4.2) & fio 2.1
