E1000 multiport nics have separate irq assigned to each "port", so having 2 x Quad-Core Xeon and 2 x 4-port e1000 would allow you to configure static affinity of each port to one core: http://bcr2.uwaterloo.ca/~brecht/servers/apic/SMP-affinity.txt Sometimes symmetric usage of network interfaces (for symmetric core usage) is the problem. I think you can achieve it by plugging all 8 ports to managed switch and configuring some form of aggregation. The best would be src/dst IP EtherChannel or something similar. For some deployments (where router sees all the clients on OSI layer 2) src/dst MAC EtherChannel would suffice. On linux side you would have to configure bonding: http://linux-net.osdl.org/index.php/Bonding pozdrawiam, Marek Kierdelewicz KoBa ISP _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
