    I find that the iostat in Linux gives the average disk queue length different from Window. Window use Little's Law, but Linux use "weighted # of milliseconds spent doing I/Os" (Last Field in /proc/diskstats) divided by the duration. I have searched in Google but I cannot find any mathematical explanation on this. Could anyone give me some pointers? :confused::confused:

          int x = 0;
          int& rX = x;

          Sorry. I too could not resist prescribing humor.

          INTJs never really joke. They make a point. The joke is just a gift wrapper.
