set the test to run, you get huge gaps. -<br>
- Say that your server always have a lot of IO every 3min for 1
min. -<br>
- You will probably miss all this IO, set it to the same as the
clientlaunch time 5min = 300 in the script. -<br>
- iostat need to run constantly to make accurate measurements.
- <br>
- That's why you see the default do 300
sec. -<br>

To get better accuracy you should probably run "iostat dxn 300 13" and
run the script from clientlaunch every hour.<br>
A bit more coding to take care of the 11 "new" iostat though.<br>

After discussion with a colleague we thought that a 2 second iostat
sample might not be adequate.<br>
We settled on 10, but with the update, I have made it a parameter,
which can be set at server side.<br>

Cheers<br>
