[Linux-cluster] noatime

[gordan at bobich.net]

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.
