.... [23] and the heuristics used by FFS [13] 3 Benchmarking File Systems and I O Performance There has been much work in the development of accurate workload and micro benchmarks for file systems [22, 24] There exists a bewildering variety of benchmarks, and there have been calls for still more [16, 19, 27]. Nearly all benchmarks can be loosely grouped into one of two categories: micro benchmarks, such as lmbench [14] or bonnie [1] which measure specific lowlevel aspects of system performance such as the time required to execute a particular system call, and macro or workload benchmarks, such as ....

....kernel assisted 23 logging. We illustrate mechanisms for coping with request reordering, packet loss, and anonymity. Heeding demonstrated requests from the OS community, these techniques lead us to suggest a new metric for measuring sequentiality that applies to both NAS and non NAS environments [2]. File system designers must remain vigilant to the different views of the file system seen by client and server even in a tightly integrated LAN environment. Our original motivation for gathering traces was to examine file system behavior and find how to design better block allocation and layout ....

....benchmarks and reporting the results are relevancy and repeatability. A benchmark needs to be relevant in that the measurements must reflect typical modes of operation in the selected problem domain [t0] and repeatable in that the target audience must be able to reproduce the results if necessary [20]. The results of the benchmarks described in section 2 are not immediately relevant in the sense considered here, because the mode of operation used corresponds to none but most trivial problem domains. The chief differences are testing individual performance factors separately, testing with no ....

....for SPEC SFS 2.0 is a throughput (NFS operations per second) versus response time graph. However, since SPEC SFS 2. 0 measures NFS server performance by generating NFS client RPCs, it cannot be used to compare NFS against other protocols, nor can it be used to test client side caching strategies [M99]. The ideal MPFS benchmark should support both CIFS and NFS protocols. NetBench NetBench is a portable I O benchmark program that measures the performance of file servers as they handle network file requests from clients. NetBench accepts as clients PCs running Windows platforms. NetBench takes ....
