I've booted with kernel profiling turned on. I've posted some preliminary results. I don't have profile data yet, but you can see in the following that when I turn off my iptables rules, the ping latency graph flattens out. http://depot.mtholyoke.edu:8080/tmp/tap-sam/2004-03-06_9:30/sam_last_108000.png http://depot.mtholyoke.edu:8080/tmp/tap-sam/ My understanding is that the kernel profile information will become interesting when the machine starts thrashing. If it would be useful for me to dump anything before then, let me know. _________________________ Ron Peterson Network & Systems Manager Mount Holyoke College - 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/
