In fact, there are actually negative consequences of doing so.įor example, for defrag to combine fragments that are 64MB or larger requires significant amounts of disk I/O, which is against the principle of minimizing I/O that we discussed earlier (since it decreases total available disk bandwidth for user initiated I/O), and puts more pressure on the system to find large, contiguous blocks of free space. Defraggler is ranked 2nd while Disk Defrag is ranked 4th.
This means that there is a point after which combining fragmented pieces of files has no discernible benefit. In Vista, we analyzed the impact of defragmentation and determined that the most significant performance gains from defrag are when pieces of files are combined into sufficiently large chunks such that the impact of disk-seek latency is not significant relative to the latency associated with sequentially reading the file.

Thus, the Windows 7 Defragmenter is competitive with the other defragmenters. Unlike its Windows XP counterpart, it does not perform as well at the boot optimization, but scores in the disciplines defragmentation and consolidation of free space. The rest of the time, Windows defrag keeps things in good shape. The Windows 7 Defragmenter does quite a decent job. Disk Defragmenter runs as a low-priority background task that kicks off once a week, in the middle of the night, without requiring any attention from you. I only use Defraggler after I have done a bunch of downloading and housekeeping-cleaning up and moving files, etc. The Disk Defragmenter in Windows 7 improves on earlier versions in many ways, not the least of which is you shouldnt need to do anything to benefit from it. The estimated time kept dropping all the way. So, which one is correct? Well, before the question can be answered we must understand why defrag in Vista was changed. I ran Defraggler this morning on a 1TB drive and it started at 18 hours and completed within 30 minutes. As a result, defrag in XP and defrag in Vista will report different amounts of fragmentation on a volume. Not so in Windows Vista if the fragments are large enough – the defragmentation algorithm was changed (from Windows XP) to ignore pieces of a file that are larger than 64MB. Learn more at Windows XP, any file that is split into more than one piece is considered fragmented. For now let's take what we have and just let me know how it turns out.īest, Shawn "Cmdr" Keene | Microsoft MVP - Windows Insider | | tweet: Microsoft MVPs are independent experts offering real-world answers. To do this you'll need to launch an administrator-mode task manager session, but I can guide you if you
If you don't think this is the case, we might need to explore more and find out just what processes are using your CPU time, RAM and drive I/O access. Your drive's lifespan, so it's a trade off like anything else. If it is, you might consider moving the scheduled one to daily instead. Once this time is done, future runs should be better since they run weekly and the drive isn't likely to become significantly fragmented that fast. If your drive is so severely fragmented that you can't just leave it until the next overnight background defrag, I'd suggest booting into Safe Mode to do it, so that nothing else is running and it will have nearly exclusive access to the drive and completeįaster.
The sad truth is that this stuff really hogs resources, and since it's impacting CPU timeslice, RAM usage, disk access, it might be seriously impacting this performance, especially since you have a mechanical hard drive instead of solid These are very numerous but include things like setting up new caches, optimizing app manifests, syncing data, cleaning up, and

If you've installed Windows 10 recently, there's a huge list of "deferred tasks" as Gabe Aul (Windows program manager) puts it.
