trait
Benchmark
extends
AnyRef
Benchmark
can be used to quickly turn an existing
class into a benchmark. Here is a short example:
object sort1 extends Sorter with Benchmark { def run = sort(List.range(1, 1000)) }
The run
method has to be defined by the user, who
will perform the timed operation there.
Run the benchmark as follows:
> scala sort1 5 times.log
This will run the benchmark 5 times and log the execution times in
a file called times.log
