For anyone interested...thanks!
Has anyone tried it? I found the last couple of versions slowed my machine to a crawl with the background defragging.
Excellent piece of software.As far as i remember it only performs a idle defrag.
I disabled the service and the tray.exe when using it.Im using defraggler at the moment.
I use it (not v16 yet as it just came out). I have background defragging off and only run a Complete defrag manually once a month or two...even then it's only 4-5% defragged.
I used to research the file movement algorithms of a number of top defragmenters back in 2005, and at that time O&O had the most polished implementation amongst competitors, working much better than PerfectDisk and Diskeeper.
I never tried newer versions, I suspect it might become a bloatware like lot of other brilliant soft.
I use version 15 and like the TRIM functionality it provides for XP. After playing around with 16 in a VM, I think I'll stay with 15.
What metrics did you use to compare them ?
I started designing UltimateDefrag at that time, and I was interested in defragmentation algorithms, specifically in single pass defragmentation and free space consolidation. There was no information on the internet, so I went ahead and started debugging existing solutions to see what they are doing.
O&O basically produced the best file layout (I mean minimum file and free space fragmentation) with the least number of file I/O operations.
One of the reasons I have always liked defrag tools that sensibly ignore large fragments is that it hugely reduces the defrag time (and I/O) for only minimal (if any) performance losses on normal desktop activities.
