I have a VPS in cloud environment based on XEN Virtualization platform.
/etc/fstab looks like that:
LABEL=PRGMRDISK1 / ext3 errors=remount-ro 0 0
As far as I know IO can pretty easily become a bottleneck if some other VPS neighbor will use it intensively(IO bandwidth is a shared resource for multiple guest VPS).
Can I add
noatime,nodiratime to /etc/fstab partition declaration to save some IO load? Will it work?
