In regards to the receive side CPU utilization improvements: I think that NAPI does a good job at least in getting ridding of the biggest offender -- interupt overload.
I disagree, at least for bulk receivers. We have no way currently to get rid of the data copy. We desperately need sys_receivefile() and appropriate ops all the way into the networking, then the necessary driver level support to handle the cards that can do this.
Once 10gbit cards start hitting the shelves this will convert from a nice perf improvement into a must have.
