+1 "me too".

In regards to OS-specific things, I am somewhat against making it have
any at all. The most desirable outcome of this draft would not be that
admin can find what to tune for HTTP, but that TCP would evolve so we
dont have to tune at all. Don't forget that HTTP applications require
many different protocols all working together over the same transport(s)
to be efficient. Tuning just for one wont help much.

Along the lines of the FQ-Codel work done by the buffer bloat guys (some
of what will be relevant here) having a strong and fair underlying
transport can make the whole system more efficient.
