The first set of values from iostat is a long accumulation that you normally
should ignore. If you give a number on the command line it will run
continuously reporting every so many seconds. A value of 1 to 5 should give
you
meaningful samples when the machine is busy.
But, that 70% iowait number pretty much tells you what the machine is doing
with
most of its time...
