Hi Xuekun - Not sure why they Q2Q N value is down 5%, but the AVG Q2Q is pretty close - only 11msec (again, about 5%). After that, things are affected by merge rates most likely - note that there were 262882 merges on the first run whilst there were only 8970 on the second run. Perhaps you could look at the blkparse output from both and get a feel for the vast reduction in merges. [Any changes on the system between the runs?] Regards, Alan -- To unsubscribe from this list: send the line "unsubscribe linux-btrace" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
