Meanwhile I'll push it all out to http://ozlabs.org/~akpm/mmots/ for the crazier testers. One thing: > Numbers can be found at https://lkml.org/lkml/2012/9/13/239 You claim in the above that the fork worload is 'slab intensive". Or at least, you seem to - it's a bit fuzzy. But how slab intensive is it, really? What is extremely slab intensive is networking. The networking guys are very sensitive to slab performance. If this hasn't already been done, could you please determine what impact this has upon networking? I expect Eric Dumazet, Dave Miller and Tom Herbert could suggest testing approaches. -- 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/
