It is always entertaining to do a "git log" and search for his name.... I especially liked the ksoftirqd related patch 3bcb846ca4cf55415d3719e64bb45a124792c589 " Depending on qdisc setup, I observed a gain of up to 19 % in qdisc performance (1016600 pps instead of 853400 pps, using prio+tbf+fq_codel= ) " --=20 Dave T=C3=A4ht Let's go make home routers and wifi faster!
