Amd is a daemon that automatically mounts filesystems whenever a file or directory within that filesystem is accessed. Filesystems are automatically unmounted when they appear to have become quiescent.

Symbolic links on an NFS file system can be incredibly inefficient. In most implementations of NFS, their interpolations are not cached by the kernel and each time a symbolic link is encountered during a lookuppn translation it costs an RPC call to the NFS server. It would appear that a large improvement in real-time performance could be gained by adding a cache somewhere. Replacing symlinks with a suitable incarnation of the auto-mounter results in a large real-time speedup, but also causes a large number of process context switches.
