So, cpuload is stable around 5.00 - 5.50. IO wait is difficult to identify. Using top I can read an average of 0% with some peaks up to 4%. Using iotop the process kjournald is jumping on first position often with peaks to 10-20%, back to 0 immediatly. Second place for nagios process. But the 1sec refresh is changing very often the situation. Semms really interesting your doc, also I'll try some solutions. I'll use sym links to not alter any configuration file. Should do the trick as well. I'll let you know!
