Simulating application disk I/O with filebench

FileBench is a framework of file system workloads for measuring and comparing file system performance. The key is in the workloads. FileBench has a simple .f language that allows you to describe and build workloads to simulate applications. You can create workloads to replace all the pre-mentioned benchmarks. But more importantly, you can create workloads to simulate complex applications such as a database. For instance, i didn't have to buy an Oracle license nor figure out how to install it on my system to find out if my changes to the vdev cache for ZFS helped database performance or not. I just used FileBench and its 'oltp.f' workload.
