The article just came out from behind the paywall for general reading and is here: http://lwn.net/Articles/564978/ (I haven't fiddled with these new features because I'm in the final throes of getting a decent beta of cerowrt out on 3.10.12 with some annoy-the-nsa features in it. ) The only benchmark I've seen on the new scheduler so far was: http://thread.gmane.org/gmane.linux.network/281023 Anybody got relevant benchmarks? I am very happy to see the TSO/GSO sizing stuff as well. I hope that this will result in GSO doing sane things on 100Mbit and slower devices. --=20 Dave T=E4ht
