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.
