Do I require to defrag MacOSX filesystems?
The equal linux inquiry advised me of the negative efficiency of my MacBookPro. I'm not also certain what the default FS nowadays is. I read someplace that there is a cron work which works on friday or saturday which does such things.
So do I require to defrag my disk? And also if, How would certainly I do that?
Adding to Glenn's solution, Amit Singh has actually done detailed screening and also created a device
hfsdebug. In his results, he concludes:
Defragmentation on HFS+quantities need to not be essential in all, or rewarding, most of the times, due to the fact that the system appears to do a great work of avoiding/countering fragmentation.
With the default documents system JHFS+ or Mac OS Extended (journaled), current variations of Mac OS X defragment some points instantly. Nonetheless, if you make use of huge documents or have a really complete disk you might gain from defragmenting.
If huge quantities of adjoining room are inhabited by numerous swapfiles at
/private/var/vm after that reactivating the System can momentarily free the room made use of by almost among those documents, therefore perhaps permit various other sorts of documents to be created-- without fragmentation-- because room.
iDefrag is one item detailed in Apple data source that additionally mentions it does not touch the "Hot Zone" which is a location of the disk made use of by OS X to maximize disk accessibility. They have a trial variation you can attempt.
