Believe me, I'd really love to do so but I really don't have any clue about CFLAGS, how to find the problematic LOCs for CPU usage, cache misses, etc. I think I wrote some previous mails about different challenges I ran into. I feel like there is a certain amount of knowledge inside of Intel and 6WIND about these things that hasn't propagated to the rest of the community. Maybe we could find a way to have some hackathons in Silicon Valley where people could work on code or projects together? Then we could see about spreading and documenting some of the organic knowledge to improve the coding and tuning guides. The Meetups seem to demo new features but they don't talk about testing and tuning there sadly. I'm really up for any ideas, it's something I struggled with ever since the beginning of when I used DPDK 1.x in 2011. Matthew.
