Oh, right. I had forgotten how dramatic the changes were in those test runs. I guess I should be happy that the absolute numbers on this machine were as high as they were. This machine seems to be beating that one on every metric. > Do you think the difference is in the CPU architecture, or the > IO subsystem? That is an excellent question. I tried looking at vmstat output, but a funny thing kept happening: periodically, the iowait column would show a gigantic negative number instead of a number between 0 and 100. This makes me a little chary of believing any of it. Even if I did, I'm not sure that would fully answer the question. So I guess the short answer is that I don't know, and I'm not even sure how I might go about figuring it out. Any ideas? > Also, do you have the latency numbers?
