| <h1>In Depth Analysis</h1> |
| |
| <p> |
| 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. |
| </p> |
| |
| <p> |
| 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. |
| </p> |
| |
| <p> |
| JetStream includes benchmarks from the SunSpider 1.0.2 and Octane 2 JavaScript |
| benchmark suites. It also includes benchmarks from the LLVM compiler open source |
| project, compiled to JavaScript using Emscripten 1.13. It also includes a |
| benchmark based on the Apache Harmony open source project's HashMap and a port of |
| the <a href="https://www.cs.purdue.edu/sss/projects/cdx/">CDx</a> benchmark, |
| hand-translated to JavaScript. |
| </p> |
| |
| <p> |
| These benchmarks cover both classical performance measurements — like Martin |
| Richards's machine and language independent benchmark (richards) and the |
| Dhrystone synthetic computing benchmark (dry.c) — and real-world examples — like |
| the Mozilla open source project's PDF renderer (pdfjs), the Box2D JavaScript |
| physics engine (box2d), and the jQuery and Closure JavaScript libraries (code- |
| first-load, code-multi-load). |
| </p> |
| |
| <p> |
| Note that scores from JetStream @VERSION@ are not comparable to scores from other versions |
| of JetStream. |
