I make some real life tests with 10Gbit traffic and make some rdos. With kernel 3.4.5 when I reach 6M routing cache entries - traffic is no= t=20 forwarded - on my hardware with 64G RAM With kernel - 3.5.0-rc7-next-20120720 + David M. patches - route cache=20 removal + fix Traffic is forwarder all the time at speed 8.2Mpps RX from traffic=20 generator and 8.2Mpps TX to the sink Also I see performance improvement. With kernel 3.4.5 I can reach maximum od 7.5Mpps with my hardware And with kernel 3.5.0-rc7-next-20120720 i can reach 8.2Mpps - forwardin= g=20 UDP performance - can be more - but my TX pktgen that use 6 cores can't= =20 do more. Really thanks for this :) BR Pawe=C5=82 Staszewski
