That advice is mostly obsolete, lazytime has been a thing for years.
- karmakaze 4y agolazytime isn't default though is it? So changing fs time options is still useful advice.
- eru 4y agoWell, same point: keeping track of atime is way too expensive and barely useful. Lazytime is a pretty good hack, but it doesn't survive a crash, does it?
- the8472 4y agoFew things need atime at all, even fewer things need synchronous durability guarantees for atime (I'm not aware of any). So writing it out in the background (either when evicting disk cache or after 24h) while keeping the in-memory representation up to date is good enough for most use-cases.
- eru 4y agoI agree. My point was that many of the items mentioned in https://news.ycombinator.com/item?id=34387703 https://news.ycombinator.com/item?id=34387703 were pointless / unnecessary.
