Inspired by this answer, I realize I have no idea how to disable the last accessed attribute in Windows to increase performance. If you can, how?

I know in Linux you can mount the partition with the 'noatime' option, but is there a similar feature in Windows for NTFS?

Oooh, this will be a good one, +1 –  Avery Payne Jun 30 '09 at 16:30
    
I split the difference between sweimann's and J Rennie's answers - they both answer the question but provide different information. –  romandas Jun 30 '09 at 17:31

fsutil behavior set disablelastaccess 1

But be careful, some program (especially backup programs) might need this.

Accepted -- nice use of fsutil. +1 went to the reg entry and the technet link from J Rennie. –  romandas Jun 30 '09 at 17:23
    
I don't see why backup programs would use it? I think such software would rely on last modified attribute instead. –  lucek Aug 3 '12 at 12:39
    
@lucek: I agree that it should but the Windows platform is full of cheap crap made by morons without a clue and unfortunately, "backup" software people use is way too often the ultra-cheap crap from the last corner of India or China that is preloaded onto equally cheap external disks or thumb drives they use for backup purposes. Since I don't trust that this stuff gets the basics done right, I wrote the warning that it might have side effects to turn these attributes off. –  Sven Aug 3 '12 at 13:04

Whether it makes much difference is debatable.

+1 for the registry entry and technet link -- I was rather torn as to which would be 'better', but wanted to promote the use of fsutil. –  romandas Jun 30 '09 at 17:24
