Without packet steering NAT masquarade speed on BCM4908 /jumps/ between two speeds: 1. 826 Mb/s (±3 Mb/s) 2. 909 Mb/s (±8 Mb/s) and it never reaches ~940 Mb/s. Proper packet steering can improve it. Below are testing results for running iperf TCP traffic from LAN to WAN. They were used to pick up golden values. ┌──────────┬──────────┬───────────┐ │ eth0 │ br-lan │ speed │ │ rps_cpus │ rps_cpus │ [Mbps] │ ├──────────┼──────────┼───────────┤ │ 0 │ 0 │ 743 / 804 │ │ 0 │ 1 │ 738 / 821 │ │ 0 │ 2 │ ✓ 940 │ │ 0 │ 4 │ ✓ 938 │ │ 0 │ 8 │ ✓ 941 │ ├──────────┼──────────┼───────────┤ │ 1 │ 0 │ 829 │ │ 1 │ 1 │ 829 │ │ 1 │ 2 │ ✓ 942 │ │ 1 │ 4 │ ✓ 941 │ │ 1 │ 8 │ ✓ 941 │ ├──────────┼──────────┼───────────┤ │ 2 │ 0 │ ✓ 942 │ │ 2 │ 1 │ 926 │ │ 2 │ 2 │ ✓ 942 │ │ 2 │ 4 │ ✓ 942 │ │ 2 │ 8 │ ✓ 941 │ ├──────────┼──────────┼───────────┤ │ 4 │ 0 │ ✓ 941 │ │ 4 │ 1 │ 925 │ │ 4 │ 2 │ ✓ 941 │ │ 4 │ 4 │ ✓ 941 │ │ 4 │ 8 │ ✓ 941 │ ├──────────┼──────────┼───────────┤ │ 8 │ 0 │ ✓ 942 │ │ 8 │ 1 │ 925 │ │ 8 │ 2 │ ✓ 941 │ │ 8 │ 4 │ ✓ 942 │ │ 8 │ 8 │ ✓ 942 │ └──────────┴──────────┴───────────┘ Ref: fcbd39689e ("bcm53xx: enable & setup packet steering") Signed-off-by: Rafał Miłecki <rafal@milecki.pl>		2022-07-28 17:46:33 +02:00
