For the right combination of budget, application and team you can get a custom solution with much lower latency. Back in the days my team beat Solarflare hands down, but only for a single application. Don't remember the total number, but each additional 4 bytes of the payload added 5-7ns, IIRC.

Yes, of cause. If you have the big-budget and great team you can optimize your application very much. But in Embox the user applications stay the same, and customization was very easy!
