Greetings,
I am aware that mounting filesystems with noatime option greatly increases speed.
I have tried to follow discussion on the pros and cons of using noatime.
I have however not been able to mount with the option relatime in centos 5.2.
But in a production db server, which is backed up by HP DP, is it advisable to mount with noatime?
Anybody care to share their experience on it?

All of my DB systems and more importantly integration and functional testing systems are noatime and there is a marked difference in performance - literally cutting testing time by at least half... There is a lot of disk I/O in that...
RHEL doesn't have a reltime enabled kernel so centos doesn't either by default. I believe that there is a kernel in plus that is reltime enabled but due to potentially breaking ABI compatibility with RHEL I don't make use of it.
