Improving Disk I/O Performance on Linux

The existing Linux disk schedulers are in general efficient, but we have identified two scenarios where we have observed a non-optimal behavior. The first is when an application requires a fixed bandwidth, and the second is when an operation performs a file tree traversal. In this paper, we address both these scenarios and propose solutions which both increase performance.
