This README is designed to give you the information you need to get running with the benchmarker and the basics of working with the code. Only in the rare case where there is a common practice like setting the buffer pool size of a database do we change any settings. These settings are recommended for consistency across services. The benchmark default settings are not tuned for any particular platform or instance type.
It's designed to operate via vendor provided command line tools. PerfKit Benchmarker is an open effort to define a canonical set of benchmarks to measure and compare cloud offerings.
