| <p>Benchmarks the 'function' returning the result as invocations per ms. args is an opaque argument passed as the second argument to the function. max_time is the total time to benchmark the function, in ms. initial_batch_size is the initial batch size to the run the function. The harness function will automatically ramp up the batch_size. The benchmark will take <em>at least</em> initial_batch_size * function invocation time. </p> |
