Thread-topic: How to optimize the UDP speed when the package is greater than the MTU

Hi All，

I try to test the performance of netfront netback

I use xen4.4 and kernel 3.17-4

When I test the UDP speed

I found that if send package is larger than the MTU, xen-back will only one queue at work.

And the speed is slow

Is there any way to makes multi queue working with package larger than the MTU or can accelerate speed

Xiaoding

Regards
