    54   --shell           Path to JavaScript shell

    55   --args            Arguments to pass to JavaScript shell

    56   --runs            Number of times to run tests (default: $testRuns)

    57   --tests           Only run tests matching provided pattern

    59   --shark20         Like --shark, but with a 20 microsecond sampling interval

    60   --shark-cache     Like --shark, but performs a L2 cache-miss sample instead of time sample

    61   --suite           Select a specific benchmark suite. The default is sunspider-0.9.1

    62   --ubench          Use microbenchmark suite instead of regular tests. Same as --suite=ubench

    63   --v8-suite        Use the V8 benchmark suite. Same as --suite=v8-v4

    64   --parse-only      Use the parse-only benchmark suite. Same as --suite=parse-only
