Hello, Im puzzled about the influence about iowait. Almost all the document
say, the iowait "Show the percentage of time that the CPU or CPUs were idle
during which the system had an outstanding disk I/O request."
And, if there was a programs writing disk frequently, the system's iowait would
be very high and the cpu was very free(do nothing). If so, the kernel's process
scheduling should work fine, but the process scheduling lantency was very
high(some programs were rescheduled after a long time). Why? Thanks
