We would love = to have users who are intent on breaking everything... all open source, no= weird IP or anything, no plan to commercialize it.

Well, the overarching goal here is to reduce latencies on everything (hardw= are, interconnects, busses, drivers, oses, stacks) to the bare minimum, on = every technology we can reach, and leverage other ideas in other technologi= es to do so, whenever possible. If we had a name for that, other than bufferbloat, I'd switch to it, becaus= e we are way beyond just dealing with excessive buffering after 6+ years of= operation. I will got read up on ken's RDMA stuff. > >>> Feel free to tinker your bayes filter if all sounds too alien.<<
