The main reason why performance improves with noatime (is the
nodiratime flag supported?) is because it means no write happens for ever
file read. That means no locking required, which is the main thing that
slows down concurrent accesses. I don't know what the first-access issue
might be, but noatime should help under heavy concurrent use.

Were you trying this for a specific reason? I tried noatime to see if I could
get a faster initial response time from the GFS volume. Every time I access
it, there is a long delay initially, then things are fine until the next
access.

Hi all,
If I put in my fstab file:
/dev/sdc5 /home gfs noatime
Will it actually mount without atime? And how can I confirm this?
Thanks.
