This is amazing work. I cant help but state that we have been doing these in HPC environments for at least 15 years - User space networking, offloads, NUMA domains aware scheduling, jitter reduction ... great to see it being put to good use in more mainstream workloads. Goes to show - software is eating the world.

I worked in HPC as well, and I have to point out emphatically that this IS NOT USERSPACE NETWORKING. The TCP stack resides in the kernel. The vast majority of our CPU time is system + interrupt time.
