Hello,

I just wondered if it would be better to mount devices using the relatime option instead of noatime? In aptosid noatime seems to be the default.

I am not sure which tools require a correct atime (the mount man page mentions mutt). But it seems that relatime might be a good compromise between atime and noatime? AFAIK ubuntu is using relatime.

Greetings,
arwa

Can't comment on noatime vs relatime, however, > http://www.google.com/linux?q=noatime+v ... lla-search

who cares about ubuntu ? Last I knew this was aptosid ,which is NO relation to ubuntu Wink

Kernel developer Ingo Molnar said the following:

Atime updates are by far the biggest IO performance deficiency that Linux has today. Getting rid of atime updates would give us more everyday Linux performance than all the pagecache speedups of the past 10 years, _combined_.

aptosid (and debian) uses relatime already
looking at
      Code:
cat /proc/mounts
will tell you.
