This object reports the Average Local Response Time (ALRT), in milliseconds, for the NFS Application Optimizer since it was started. An administrator monitoring NFS-based file access over a WAN can use it to see how quickly requests are being answered locally by the AO rather than waiting on the remote file server. For example, a low, stable ALRT would indicate the NFS AO is successfully accelerating file reads for branch-office clients accessing a central NFS server.
