JBenchXA new version of JBenchX is available! This release fixes some bugs and brings a cool new feature:
The @ForEachType annotation. It is best explained with an example:
@Bench
public Object createObjectArray(@ForEachInt({10,100,1000}) int size) {
return new Object[size];
}
This will tell JBenchX to run the benchmark once for each given size!
Initializing Benchmarking Framework... Running on Linux Linux Max heap = 1392508928 System Benchmark = 21.6ns Performing 3 benchmarking tasks.. [0] Example3.createObjectArray(10)************* 36.3ns [1] Example3.createObjectArray(100)********** 283ns [2] Example3.createObjectArray(1000)************ 2.40us Success.
There are annotations for all matching java base types: @ForEachBoolean, @ForEachDouble, @ForEachFloat, @ForEachInt, @ForEachLong, @ForEachString.
Another new feature you can see from the output above is that JBenchX prints some basic information about the system that is used for running the benchmark. It also computes a system benchmark. This is useful to detect changes in the load of your computer which will affect the benchmark result!
