Why is this interesting to anyone?
Haven't we all moved to https by now?
Optimizing raw http seems to me like a huge waste of time by now.
I say that as someone who has spent years optimizing raw http performance.
None of that matters these days.
For me the interest comes from seeing the speed boost between regular kernel/optimized kernel/DPDK. What you put behind the RX layer doesn't really matter, but it's good to see numbers and things to do when your RX system isn't giving you enough throughput.
