Any recomendation ? what about a combo ethernet cards ? . On a SMP machine how is IRQ assigned so that every diiferent netcard is assigned to different CPU. PS. It seems that nobody had test the troughput of linux networking.. If u have a link to such test pls give me a link.. Some info on which network cards offloads CPU more.. or any info u can give me on the possible max and sustained throughput on modern x86 computer. | _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
