Steady improvements in storage capacities and CPU clock speeds intensify the performance
bottleneck at the I/O subsystem of modern computers. Caching data can efficiently short …

As the performance gap between disks and micropocessors continues to increase, effective
utilization of the file cache becomes increasingly immportant. Application-controlled file …

Most file systems attempt to predict which disk blocks will be needed in the near future and
prefetch them into memory this technique can improve application throughput as much as …

Two contributions are made in this paper. First, we show that system level characterization of
file block references is inadequate for maximizing buffer cache performance. We show that a …

As disk performance continues to lag behind microprocessors and memory systems, the file
system is increasingly becoming the bottleneck for many applications. This dissertation …

Cache management in flexible filesystems deals with the problem of determining a cached
file to be replaced when the local cachespace is exhausted. In analogy to virtual memory …

Prefetching and caching are widely-used approaches for improving the performance of file
systems. A recent study shows that it is important to integrate the two, and proposed an …

Prefetching and caching are effective techniques for improving the performance of file
systems, but they have not been studied in an integrated fashion. This paper proposes four …
