I booted your latest patch on a 4-way SMP box (1.5 GHz, 9MB ia64). This is what it produces. I think the estimate is excellent. [00]: - 10.4(0) 10.4(0) 10.4(0) [01]: 10.4(0) - 10.4(0) 10.4(0) [02]: 10.4(0) 10.4(0) - 10.4(0) [03]: 10.4(0) 10.4(0) 10.4(0) - --------------------- cacheflush times [1]: 10.4 (10448800) One other minor thing: when booting a numa kernel on smp box, there is a numa scheduler domain at the top level and cache_hot_time will be set to 0 in that case on smp box. Though this will be a mutt point with recent patch from Suresh Siddha for removing the extra bogus scheduler domains. http://marc.theaimsgroup.com/?t=111240208000001&r=1&w=2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
