To show some difference below comparision vlan/no-vlan traffic 10Mpps forwarded traffic vith no-vlan vs 6.9Mpps with vlan (ixgbe in kernel driver kernel 4.13.0-rc4-next-20170811) ethtool settings for

still free cpu cycles so probabbly can forward at line 10G rate 14Mpps Average: CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle Average: all 0.00 0.00 0.00 0.00 0.00 20.91 0.00 0.00

Hi I made some tests for performance comparison.Thanks for doing this. Feel free to Cc me, if you do more of these tests (so I don't miss them on the mailing list). I don't understand stand if you are reporting a potential problem? It would be good if you can provide a short summary section (of the issue) in the _start_ of the email, and then provide all this nice data afterwards, to back your case. My understanding is, you report: 1. VLANs on ixgbe show a 30-40% slowdown 2. System stopped scaling after 7+ CPUsThis is not only problem/bug report - but some kind of comparision plus some toughts about possible problems :) And can help somebody when searching the net for possible expectations :) Also - dono better list where are the smartest people that know what is going in kernel with networking :) Next time i will place summary on top - sorry :)quoted

You could be stalling on DMA TX completion being too slow, but you already increased the interval and increased the TX ring queue size. You could play with those setting and see if it changes this? Could you try my napi_monitor tool in: https://github.com/netoptimizer/prototype-kernel/tree/master/kernel/samples/bpf Also provide the output from: mpstat -P ALL -u -I SCPU -I SUM 2with 16 cores / 16
