sysbench is a scriptable multi-threaded benchmark tool based on LuaJIT. It is
most frequently used for database benchmarks, but can also be used to create
arbitrarily complex workloads that do not involve a database server.

sysbench comes with the following bundled benchmarks:
- oltp_*.lua: a collection of OLTP-like database benchmarks
- fileio: a filesystem-level benchmark
- cpu: a simple CPU benchmark
- memory: a memory access benchmark
- threads: a thread-based scheduler benchmark
- mutex: a POSIX mutex benchmark
