Here we go: http://www.kernel.org/pub/linux/kernel/people/andrea/misc/31-44-100-1000/31-44-100-1000.html the global quips you posted indeed had no way to account for the part of the curve where 4:4 badly hurts. details in the above url. Please cross check my results on your hardware (I used a 2.5Ghz xeon, 1G of ram, and benchs run fresh after boot with all ram still free). Numbers are perfectly reproducible for me, and they make perfect sense too. 2.6.5-aa4 is the same as 2.6.5-aa3 for this benchmark (though I'll upload 2.6.5-aa4 in a few hours). - 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/ | ||||||||||||
