Rafał Miłecki fcbd39689e bcm53xx: enable & setup packet steering ... Packet steering can improve NAT masquarade performance on Northstar by 40-50%. It makes reaching 940-942 Mb/s possible on BCM4708 (and obviously BCM47094 too). Add scripts setting up the most optimal Northstar setup. Below are testing results for running iperf TCP traffic from LAN to WAN. They were used to pick up golden values. ┌──────────┬──────────┬────────────────────┬────────────────────┐ │ eth0 │ br-lan │ flow_offloading=0 │ flow_offloading=1 │ │ │ ├─────────┬──────────┼─────────┬──────────┤ │ rps_cpus │ rps_cpus │ BCM4708 │ BCM47094 │ BCM4708 │ BCM47094 │ ├──────────┼──────────┼─────────┼──────────┼─────────┼──────────┤ │ 0 │ 0 │ 387 │ 671 │ 707 │ 941 │ │ 0 │ 1 │ 343 │ 576 │ 705 │ 941 │ │ 0 │ 2 │ ✓ 574 │ ✓ 941 │ 704 │ 940 │ │ 1 │ 0 │ 320 │ 549 │ 561 │ 941 │ │ 1 │ 1 │ 327 │ 551 │ 553 │ 941 │ │ 1 │ 2 │ 523 │ ✓ 940 │ 559 │ 940 │ │ 2 │ 0 │ 383 │ 652 │ ✓ 940 │ 941 │ │ 2 │ 1 │ 448 │ 754 │ ✓ 942 │ 941 │ │ 2 │ 2 │ 404 │ 655 │ ✓ 941 │ 941 │ └──────────┴──────────┴─────────┴──────────┴─────────┴──────────┘ Above tests were performed with all eth0 interrupts handled by CPU0. Setting "echo 2 > /proc/irq/38/smp_affinity" was tested on BCM4708 but it didn't increased speeds (just required different steering): ┌──────────┬──────────┬───────────┐ │ eth0 │ br-lan │ flow_offl │ │ rx-0 │ rx-0 │ oading=0 │ │ rps_cpus │ rps_cpus │ BCM4708 │ ├──────────┼──────────┼───────────┤ │ 0 │ 0 │ 384 │ │ 0 │ 1 │ ✓ 574 │ │ 0 │ 2 │ 348 │ │ 1 │ 0 │ 383 │ │ 1 │ 1 │ 412 │ │ 1 │ 2 │ 448 │ │ 2 │ 0 │ 321 │ │ 2 │ 1 │ 520 │ │ 2 │ 2 │ 327 │ └──────────┴──────────┴───────────┘ Signed-off-by: Rafał Miłecki <rafal@milecki.pl>		2022-06-24 07:39:51 +02:00
