Says the man who has managed to post over 3,000 times on a forum for a no name software company. Who really has nothing better to do with their life than spend every waking hour for the past few years, reading and responding to every post in this forum? I dont see it ever being addressed, this product certainly seems abandoned. The developer can't be bothered to make quick bug fixes like the incorrect volume size being displayed which I reported well over a month ago. But look at how quick they are to censor the posts of customers. Piriform has plenty of people who could be working on the product, they'd rather just try to gain (or perhaps more accurately maintain) market share by pretending their competition doesn't exist. Further confirming that this product has been abandoned. Just look at the version history, its been almost a year since a release from them. And if you go through it entirely you can see initially they spent a lot of time developing the product as indicated by their frequent releases, which over time taper off as they lose interest in this product. Defraggler is dead: https://www.piriform.com/defraggler/version-history

Wow, so you guys actively do censor posts from customers where they demonstrate that competitors products work when your bug ridden product does not. Good job losing a potential paying customer for life. I'd think you'd want to court the type of people who have 8x 4TB RAIDs (among other rediculous specs) in their home computers, since they often work in IT professionally, and have the ability to procure software on a large scale. And i'm not sure why you called that a "network product". The only reason I was running the server version is because that license is required to run it on a server OS, and I'm running 2012 R2 Server because Windows 8.1 doesn't offically support ReFS. And its not like anyone isnt going to know what software it is anyways, its not like there are a lot of defragging products which support ReFS.

Yes they are Nergal. Is there any reason they dont show up under the Defraggler Bug Reporting part of this forum? The earliest post I see is from 01-28-15. Also for comparision, [a network product I use] doesn't have a problem loading my RAID, ( [ ] = Moderator edit of competition product removal -nergal )

I would have to agree with OP. I had posted a bug about the rediculously low loads it was placing on my 8 disk RAID 6, but it looks like Piriform deleted it for whatever reason. I can see Defraggler is loading only a one and a third cores, and I can only guess it will take it at least a month to defrag the 4+ TB of fragmented files I have. The only reason I use this is because it supports ReFS and is free. If they made it not suck [eggs] (and be like [another product] i'd consider paying for it. I had also filed another bug report about it not properly displaying volume sizes 10TB and over, that got deleted too.

When defragging a 18TB RAID 6 which is formatted as ReFS, Defraggler is exhibiting exceptionally poor performance and is barely placing a load on the disks at all. When it defrags large files I can see disk activity spike to 100% during that file, but when it is defragging very small files (which I have over a million of) disk activity is almost non-existant. Please note that I am aware of the exceptionally poor write performance of ReFS, and the write performance implications of using RAID 6. Its almost as if it is calling Sleep(1000) (or sleep(1)) after it defrags each file, or that the relevant thread is blocking for one second for some other reason after each file. If you look at the first attached picture (Untitled.png), at the left most portion of the Active Time graph is when it was defragging small files, and the rest of it is with large files. In the second picture (Untitled2.png) you can see it defragging some medium sized files, and take note of the pauses in the Active Time graph between each file. And in the third picture (Untitled3.png) you can see it defragging some small files, disk activity is almost nil. If it matters the relevant parts of my system are: Defraggler 2.18.945 x64 Windows Server 2012 R2 Datacenter (latest patches & activated) SuperMicro X9DAE Motherboard (Dual Xeon E5-2650, 48GB DDR3 ECC RDIMM, UEFI mode, latest BIOS) HighPoint 4320 3 Gbps SAS RAID Card with 8x 3TB HGST (HDS72303) disks in a 18TB usable RAID 6 (64k stripe, 4k sector) which is formatted as ReFS.

It appears as if Defraggler will not correctly report the volume size in the Properites area of the drive tab. I have a 18TB ReFS volume, it reports the capacity is 8,002,825,183,232 bytes but also that it is 16.4TB, and that there is 4,796,935,921,664 bytes free which also happens to be 13.5TB! I can only assume that the text box has it's horizontal size limited and is not rendering the left most "1"s which should be there even though there is ample room between it and the text box which says "Free space:" or "Capacity:". Please see the attached pictures.

Edit: Ugh, well for whatever reason the forum appears to be resizing my image to about 50% of its size. The relevant info which was displayed there is in my post above. Edit 2: I attched a second picture which will show how the information is displayed incorrectly.
