Defraggler can take over 24 hours to defrag a 150 GB disk that has already been defragged that is only 37% full !!!
It will spend several hours in the same location defragging the Freespace
I have never seen a defrag program run so slowly.
It spends nearly 50% of the time doing nothing, neither reading nor writing.
After running the defraggler to completion, which may take more than 24 hours, if I run the dfraggler again, it will spend more than 12 hours doing more work !!! If it is properly dfragged in the first run, what is it doing on the second run ???
It would be a GREAT program if only it ran to completion in a reasonable mount of time.
You have got to be kidding me with the performance of this utility.
