|
|
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.
|
|
|
|
**Features of SysBench**
|
|
|
|
* file I/O performance
|
|
* scheduler performance
|
|
* memory allocation and transfer speed
|
|
* POSIX threads implementation performance
|
|
* database server performance
|
|
|
|
|
