s it necessary? That is entirely up to your individual requirements.
SSD devices do not have seek or rotation delays, so the performance (and power consumption) is different than if you are using mechanical disk drives. If performance is of any concern, run your own tests, with and without the option, and determine if there is any perceived performance benefit from disabling atime recording. To add the option to fstab(5), include it in the fs_mntops string, as described in the fstab(5) man page. |

If its no big deal I don't want to play with a perfectly stable system. I will just keep using it and if I notice performance deterioration I will think about adding it to fstab.
Thanks for the info. BTW, do you use a SDD. Have you enabled noatime ? Just trying to get an idea about how people use SSDs under OpenBSD. Last edited by bsd007; 26th October 2017 at 12:57 PM. |

I use noatime with SSDs and spinning rust just by default. It's information I don't ever use so why spend the cycles writing it?
Is there a performance or SSD life expectancy benefit? I have no idea. It's not worth the effort for me to find out. Again, it's info I have never needed and it takes a second, one time, to add it to the fstab. That's my take on it. Other's needs/experiences may vary. |

I no longer have any mechanical drives. At one time I used it on a small netbook to try to reduce power consumption and improve I/O performance. There was no observable performance improvement for my application mix, however.
I have found atime metadata to be helpful for some problem diagnostics and some security audits, so I use it on all systems I operate. Storage is SSD, except on my Alix systems, where I use compact flash. These days, I only use noatime with async, when initiation a restore(8) on a newly formatted filesystem. |

Yup. Because he's using a root CA your browser does not recognize.

Both of my laptops still use spinning rust drives, so I always use noatime to stretch the battery a little further.
