Hi,
when i start defraggler for my small drives a single file with the size of about 10MiB going to be "defraged" within no time. The Size of the volume is 50GiG. The same fragmented File on a 1TB Disk needed about 5 Sekonds to be defraged - sounds not much - but the whole defragment process takes about 24h on the 1TB Disk. Well, after the first run of defraggle i tried to just defragment some single files - but the time for defragmenting 100 files of 10 mb is about 10 mins. The measured drive speed for both drives are about 60MB/s (SATA) on a Q9450 System with 4Gig of Ram/Win XP64.
When i defag some single files on the large volume defraggler needs a long time before an action (read/write) is indicated - what i mean is a few seconds nothing happened, then a short "flicker" of read/write activity and then a long pause before the new "shown" acitivity. Also defraggler is only using 25% (1 core) for the defrag process - on very short time periods there is something about 35%. Would be nice if defraggler could use more than one core for a longer time period -> maybe then it would be faster on large volumes.
The Drives are both formated with NTFS.

PS As you could read here the problem seems to be the large drive not NTFS/FAT32.
