Final step for gact RCU operation : 1) Use percpu stats 2) update lastuse only every clock tick to avoid false sharing 3) Remove spinlock acquisition, as it is no longer needed. Since this is the last contended lock in packet RX when tc gact is used, this gives impressive gain. My host with 8 RX queues was handling 5 Mpps before the patch, and more than 11 Mpps after patch. Tested: On receiver : dev=eth0 tc qdisc del dev $dev ingress 2>/dev/null tc qdisc add dev $dev ingress tc filter del dev $dev root pref 10 2>/dev/null tc filter del dev $dev pref 10 2>/dev/null tc filter add dev $dev est 1sec 4sec parent ffff: protocol ip prio 1 \ u32 match ip src 7.0.0.0/8 flowid 1:15 action drop Sender sends packets flood from 7/8 network Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Alexei Starovoitov <ast@plumgrid.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Acked-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: David S.
