| <h2>In-Depth Analysis</h2> |
| |
| <p> |
| JetStream 2 combines together a variety of JavaScript and Web Assembly benchmarks, covering a variety of |
| advanced workloads and programming techniques, and reports a single score that |
| balances them using a geometric mean. |
| </p> |
| |
| <p> |
| Each benchmark measures a distinct workload, and no single optimization |
| technique is sufficient to speed up all benchmarks. Some benchmarks demonstrate tradeoffs, and |
| aggressive or specialized optimizations for one benchmark might make another benchmark slower. |
| JetStream 2 rewards browsers that start up quickly, execute code quickly, and continue running smoothly. |
| </p> |
| |
| <p> |
| Each benchmark in JetStream 2 computes its own individual score. JetStream 2 weighs each |
| benchmark equally, taking the geometric mean over each individual benchmark's score to compute |
| the overall JetStream 2 score. |
| </p> |
| |
| <p> |
| It's not enough to just measure the total running time of a workload. |
| Browsers may perform differently for the same JavaScript workload depending on how many times it |
| has run. For example, garbage collection runs periodically, making some iterations take longer than |
| others. Code that runs repeatedly gets optimized by the browser, so the first iteration |
| of any workload is usually more expensive than the rest. |
| </p> |
| |
| <p> |
| For most of the JavaScript benchmarks in JetStream 2, individual scores |
| equally weigh startup performance, worst case performance, and average case |
| performance. These three metrics are crucial to running performant JavaScript |
| in the browser. Fast startup times lead browsers to loading pages more quickly. Good |
| worst case performance ensures web applications can run without hiccups. Fast average |
| case performance makes it so that the most advanced web applications can run at all. |
| </p> |
| |
| <p> |
| For JetStream 2's Web Assembly benchmarks, individual scores equally weigh startup time and |
| total execution time. An important component of JetStream 1 were the asm.js subset of benchmarks. With the release |
| of Web Assembly, the importance of asm.js has lessened since many users of asm.js are |
| now using Web Assembly. JetStream 2 has converted many of the asm.js benchmarks from |
| JetStream 1 into Web Assembly. |
| </p> |
| |
| <p> |
| All but one of JetStream'2 JavaScript benchmarks run for N iterations, where |
| N is usually 120. JetStream 2 reports the startup score as the time it takes to run the first iteration. |
| The worst case score is the average of the worst M iterations, excluding the first iteration. |
| M is always less than N, and is usually 4. The average case score is the average |
| of all but the first iteration. These three scores are weighed equally using the geometric |
| mean. |
| </p> |
| |
| <p> |
| JetStream 2 also includes a JavaScript benchmark named WSL. WSL is an implementation of a |
| GPU shading language written in JavaScript. WSL does not use the above mechanism for scoring |
| because it has a long running time. Instead, the WSL benchmark computes its score as the |
| geometric mean over two metrics: the time it takes to compile the WSL standard library, and the time |
| it takes to run through the WSL specification test suite. |
| </p> |
| |
| <p> |
| JetStream 2 includes parts of these benchmark suites that came before it: <a href="https://webkit.org/perf/sunspider/sunspider.html">SunSpider</a>, |
| <a href="https://developers.google.com/octane/">Octane 2</a>, <a href="https://browserbench.org/JetStream1.1/">JetStream 1</a>, |
| <a href="https://browserbench.org/ARES-6/">ARES-6</a>, and <a href="https://v8.github.io/web-tooling-benchmark/">Web Tooling Benchmark</a>. |
| JetStream 2 also includes new benchmarks inspired by <a href="https://krakenbenchmark.mozilla.org">Kraken</a>. |
| JetStream 2 also includes a new set of benchmarks that measure the performance of Web Assembly, Web Workers, |
| Promises, async iteration, unicode regular expressions, and JavaScript parsing. |
| </p> |
| |
| <p> |
| Note that scores from JetStream 2 are not comparable to scores to other versions |
| of any JetStream benchmark. |
