Introduction

Always a need to understand the problem before making changes.

Good topic for a paper for that reason.

Want to optimize for the common use---make sure we understand what the common use is.

Somewhat of a follow-up study of Sprite study focusing on I/O bottleneck. Done for Unix and NT workloads.

Areas of focus:

• Determine how disk behavior is affected by workload and file system parameters.

• Impact of caching.

• Impact of memory-mapped files.

• Effect of write-delay.
