Budget Fair Queueing (BFQ) Storage-I/O Scheduler

The S Benchmark Suite

A few years ago, I implemented a suite of benchmarks for evaluating various figures of merit of storage-I/O schedulers. This suite has then become an independent project. We have named it S, and you can find it here.

A GUI for S is being developed too.

A brief description of the benchmarks follows, whereas this technical report contains a detailed description of the suite and of the motivations for which we decided to implement a new suite instead of using one of the existing one.

The suite contains one benchmark for each of the following performance indexes:

Every benchmark mimics, or is actually made of, real-world I/O tasks.
