Open Source Development Labs (OSDL) have developed three freely available realworld database workloads to characterize the performance of the Linux kernel. These customizable workloads are modeled after the Transaction Processing Performance Council's industry standard W, C, and H benchmarks, and are intended for kernel developers with or without database management experience. The Scalable Test Platform can be used by those who do not feel they have the resources to run a large scale database workload to collect system statistics and kernel profile data. This paper describes the kind of real world activities simulated by each workload and how they stress the Linux kernel.
