Mounting filesystems with noatime

I was reading about the speed increases you can get by using the noatime option for mounts but apparently some programs do rely on it. The only ones I found were mutt and tmpwatch, none of which I use... Do any other parts of Arch rely on atimes or can it safely be turned off if no known dependent programs (mutt etc.) are used?

Re: Mounting filesystems with noatime

I'm using mutt and have noatime on all my partititons. It works fine. How does mutt rely on atime? This wakes up my curiosity. Thanks for any info.

Re: Mounting filesystems with noatime

I'm not sure since I have never used it. I was reading mailing lists and people were saying with certain configurations it just won't work without atimes. But on the mailing list they were talking about putting a more efficient relatime in to the kernel which would work with mutt, tmpwatch etc.

Re: Mounting filesystems with noatime

Keep in mind that relatime is only theoretically "more efficient", not really practically, at least not significant. Only noatime makes a difference, I would say.

I need real, proper pen and paper for this.

Re: Mounting filesystems with noatime

I've been running with noatime for a few days now and I haven't noticed any issues... but I also haven't noticed any speedup...
