| <h2><span id="logo">☀</span>SunSpider JavaScript Benchmark</h2> |
| |
| <p>This is SunSpider, a JavaScript benchmark. This benchmark tests the |
| core JavaScript language only, not the DOM or other browser APIs. It |
| is designed to compare different versions of the same browser, and |
| different browsers to each other. Unlike many widely available |
| JavaScript benchmarks, this test is:</p> |
| |
| <dl> |
| <dt>Real World<dt> |
| <dd>This test mostly avoids microbenchmarks, and tries to focus on |
| the kinds of actual problems developers solve with JavaScript today, |
| and the problems they may want to tackle in the future as the language |
| gets faster. This includes tests to generate a tagcloud from JSON |
| input, a 3D raytracer, cryptography tests, code decompression, and |
| many more examples. There are a few microbenchmarkish things, but they |
| mostly represent real performance problems that developers have |
| encountered.</dd> |
| |
| <dt>Balanced<dt> |
| <dd>This test is balanced between different areas of the language and |
| different types of code. It's not all math, all string processing, or |
| all timing simple loops. In addition to having tests in many |
| categories, the individual tests were balanced to take similar amounts |
| of time on currently shipping versions of popular browsers.</dd> |
| |
| <dt>Statistically Sound<dt> |
| <dd>One of the challenges of benchmarking is knowing how much noise |
| you have in your measurements. This benchmark runs each test multiple |
| times and determines an error range (technically, a 95% confidence |
| interval). In addition, in comparison mode it tells you if you have |
| enough data to determine if the difference is statistically |
| significant.</dd> |
| |
| </dl> |

| <small>(When you run the benchmark, be patient - it loops through all of the |
| test cases five times and can take a minute or longer to complete.)</small></p> |
