I am using PF_RING aware ixgbe ( simple "insmod ixgbe.ko" ) on a Dell server(8 core CPU ) for Tx and TNAPIv2 enabled ixgbe on the Rx interface on a HP server ( 32 core CPU ). Both sides have dca and ioatdma. pfsend on eth0 using a .pcap file is not exceeding 3.8 Gbps ( which is OK considering it is not DNA or TNAPI ), but on the Rx interface I see some strange number.
1. First the ifconfig tnapi0 Rx stats don't go up when no application is reading from the interface ( which is OK I think and I guess is a change because of the TNAPI changes to driver or transparent_mode=2 I am using at pf_ring insmod) . But I do see correct number of bits pumped from the Tx port 9 ( approx 3.5 GB data after 8 secs , giving one second approx for each bit ) 2. The pfcount_multichannel using "pfcount_multichannel -i tnapi0" is showing only about 300 Mbps aggregate on all 16 channels ( this is a 32 core HP server ). The first channel ( 0 ) seems to attract more traffic - around 250 Mbps and the rest 15 channels are like 5 to 10 Mbps each. Something is seriously wrong in my config. I have added pf_ring.ko ( from 5.1.0 svn ) with transparent_mode=2 and ixgbe.ko with ( MQ=32,32 RSS=32,32 ). Also tried with ( MQ=1,1 and RSS=0,0,0,0 ), ( RSS=0,0,0,0 ) and plain insmod ixgbe.ko. Only thing I haven't tried so far is ( just RSS=32,32,32,32 ). With plain ixgbe.ko insert and pfcount I am getting around 800 Mbps initially but is steadily falling off... Thanks !
