[time-nuts] Best OS for small time server

[Didier Juges]

Atime implementation on Linux (and I suspect maybe other *nix as well) was,
well, bad, maybe still is. Even if files are in the cache, the OS will
update atime on the disk.

There were talks of fixing that on Linux a while back, I am not sure if it
has been done. I lost track.

In the mean time, -o noatime is a nice option when available, I suspect it
will improve performance even on systems with fast hard drives. Setting
noatime requires a reboot (or a remount).
