That is, every time I try to look at which numa node belongs it always retu= rns -1. $ cat /sys/bus/pci/devices/0000\:04\:00.1/numa_node -1 $ cat /sys/bus/pci/devices/0000\:04\:00.0/numa_node -1 Using lstopo, I confirm that all PCI cards are "outside" of any Numa node. I have read in previous posted messages in dpdk-dev community that this is = normal in Nehalem generation Xeon architecture and there is nothing I can d= o about it. Can somebody confirm this? If so, what implications could this have on packet capture and performance? Are the NICs available in my DPDK applications? Do I have to specifically "= add" them by "-w 04:00.1 - w 04:00.0"? Is RSS supported and usable from the DPDK application? Thanks a lot for your attention Victor ________________________________ Este correo electr=F3nico y, en su caso, cualquier fichero anexo al mismo, = contiene informaci=F3n de car=E1cter confidencial exclusivamente dirigida a= su destinatario o destinatarios.
