 """Runs Apple's JetStream benchmark.
 
 JetStream combines a variety of JavaScript benchmarks, covering a variety of
 advanced workloads and programming techniques, and reports a single score that
 balances them using geometric mean.
 
 Each benchmark measures a distinct workload, and no single optimization
 technique is sufficient to speed up all benchmarks. Latency tests measure that
 a web application can start up quickly, ramp up to peak performance quickly,
 and run smoothly without interruptions. Throughput tests measure the sustained
 peak performance of a web application, ignoring ramp-up time and spikes in
 smoothness. Some benchmarks demonstrate tradeoffs, and aggressive or
 specialized optimization for one benchmark might make another benchmark slower.
