SysBench
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
Current features allow to test the following system parameters:
-
file I/O performance
-
scheduler performance
-
memory allocation and transfer speed
-
POSIX threads implementation performance
-
database server performance
