Just to throw another firework into the fire whilst people are awake, NAPI does not seem to scale to this sort of load, which was disappointing, as we were hoping it would solve some of our interrupt load problems ...
Stupid question, are you sure you have CONFIG_E1000_NAPI enabled?
NAPI is also not the panacea to all problems in the world.
I bet your greatest gain would be obtained from going to Tux and using appropriate IRQ affinity settings and making sure Tux threads bind to same cpu as device where they accept connections.
It is standard method to obtain peak specweb performance. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
