Passive NFS Tracing of Email and Research Workloads

We present an analysis of a pair of NFS traces of contemporary email and research workloads. We show that although the research workload resembles previously-studied workloads, the email workload is quite different. We also perform several new analyses that demonstrate the periodic nature of file system activity, the effect of out-of-order NFS calls, and the strong relationship between the name of a file and its size, lifetime, and access pattern.
