[Bug 919429] Re: Munin "IO Service Time" graph gives completely implausible numbers

[Tel]

Here is the offending graph, from munin. NOTE: the purple line is the
fast drive, and the yellow line is a slower drive, but for some strange
reason the yellow line goes DOWN under additional load (should go UP I
would expect). Also, the results are completely the other way to the
latency graph.
