Static NFS mounts vs autofs direct map mounts
Do you use static nfs mounts or automount? If you use automount, the mount needs to get re-established if not acessed for a while, thus delaying the first page load.
It's actually hard to argue one way or the other. The only item I can point out (happened to me) is that if you are using static mounts as in fstab and someone/thing makes an error the system may not boot and you'll have to go into rescue mode to get the system back online. That won't happen when using autofs.
