NAME
sysbench - multi-threaded benchmark tool for database systems
SYNOPSIS
sysbench [common-options] --test=name [test-options] <command>
Commands: prepare run cleanup help version
DESCRIPTION
SysBench is a modular, cross-platform and multi-threaded benchmark tool for evaluating OS parameters that
are important for a system running a database under intensive load.
The idea of this benchmark suite is to quickly get an impression about system performance without setting
up complex database benchmarks or even without installing a database at all.
The design is very simple. SysBench runs a specified number of threads and they all execute requests in
parallel. The actual workload produced by requests depends on the specified test mode. You can limit
either the total number of requests or the total time for the benchmark, or both.
Compiled-in database drivers:
• mysql - MySQL driver
• pgsql - PostgreSQL driver
Compiled-in tests:
• fileio - File I/O test
• cpu - CPU performance test
• memory - Memory functions speed test
• threads - Threads subsystem performance test
• mutex - Mutex performance test
Available test modes are implemented by compiled-in modules, and SysBench was designed to make adding new
test modes an easy task. Each test mode may have additional (or workload-specific) options.
