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.
