[Qemu-devel] is there a way to optimize vhost of virtio-net

[yue]

hi, jasowang:
     according to my test , the vm's network performance is just 20% of 
physical ethernet, the thread of vhost  easily eat up 100% cpu when under 
pressure.
when using multi queue(two queues) the performance goes up by 50%, but it uses 
more threads.
if we can come to a conclusion that vhost is bottomneck?  or do you have any 
idea to improve , first we do not need to care how  violent  the idea   is.




thanks
