Sensitivity to CPU Load?

Recommended Posts

On a WIn XP SP2 computer, I have IOBit stop defrag when 90% is attained.

Thus, how sensitive is IOBIT Defrag 5.01 to this number since my CPU

could do alot of program swapping to disk and achieve this momentarily.

Thus, two programs switching back and forth can bounce between 90%

and 30% as they swap back and forth. As a result, IOBIT defrag doesn't

seem to run even when the disk is 8% fragmented.


Perhaps, IOBIT defrag should not depend on an instantaneous/peak

cpu load factor of 90%, but use a running average of cpu loading to

test whether it achieves 90% over a fixed amount of time. This will

allow IOBIT defrag to at least start an auto defrag session so that

my disk can be defragged. Otherwise it could sit there for hours

waiting for the peak load to decrease - but in my case it never will, since I can't

control the program swapping. In addition, hopefully IOBit Defrag

factors out the CPU % load that it generates while running. If IOBit plus other

programs hit 90%, defrag would be postponed until it goes below 90%.

Note: 90% could be any number I set for the auto defrag cpu load setting.

In my case I was trying to make IOBit run since 90% doesn't always get generated,

thus guaranteeing that IOBit defrag will run.


A possible cause of program swapping is due to a limited amount of memory

available to the WIN XP Pro SP2 OS, vs. the two applications, thus forcing

the ping-pong swapping effect.
