Hello Tommy, Thank you for sharing this. Going through the slides of WWDC17, I have some clarification questions: a) the slides only plot WiFi when talking about the 'user-space', does that also apply to the cellular link? I ask this because the user-space packet io needs a different driver for different links as far as i know. b) does the user space networking always performs better than the kernel counterpart?
