new Benchmark(

}
);
Run any Benchmark example, using Perlish responders suite. Output will look like the following:

This is Benchmark's default responders suite, which generates an output similar to Perl's Benchmark.pm
Explaining the previous example:
First line describes the browser running the benchmark.
Second line gives a brief benchmark summary: what functions are to be run? for how long?
Next, there is a block summarizing each method timing results. There is one line per method, ordered alphabetically. Each such line contains:
Next, there's the comparison block: it presents the relative performance of each method compared to all others. There is one line per method, ordered by the averate running rate. Each such line contains:
this method it's ABC% slower than method X
this method it's ABC% faster than method X
Finally, there's benchmark duration summary block:
None.
No bugs have been reported.
