I am trying to run Defraggler V2.22.995 and it is really slow. Granted I have a large disk. It is a 29TB RAID 0 that is only about a third full. Defraggler says that I have 717 files that are fragmented, with 16,842 fragments, and 43% Fragmentation. After running for 15 hours it is still only 1% finished and it has not even come up with an estimated time to complete. I checked the resource monitor and the program is only reading and writing at around 6 KB/s. At that rate, it will take approximately 52.8 years to defrag the drive. Unfortunately I will be dead by then, but hopefully my grandchildren will be around to see it complete.
The disk is capable of reading and writing at about 400MB/s. That is about 66 thousand times faster than the Defraggler program is reading and writing. I have 192Gig of RAM and 2 - 12 core Xeon processors running at 3.2 GHz. I have turned off VSS and the other advanced options that are recommended to speed up defrag, but that did not help. I an running Windows 10 Pro 64bit. Does anybody have any suggestions, because at this rate, it is totally unusable.
I see recommendations to let windows built-in optimize and defrag routine do the defragging and optimizing, and only use Defraggler to defrag a couple of the worst fragmented files, but that seems to make Defraggler a rather limited tool.
