FioSynth is a benchmark tool used to automate the execution of storage workload suites and to parse results. It contains a base set of block level storage workloads, synthesized from production I/O traces, that simulate a diverse range of Facebook production services. It is useful for predicting how a storage device will perform in realistic production environments and for assisting with performance tuning.
