37 <h2><span id="logo">☀</span>SunSpider 0.9.1 JavaScript Benchmark</h2> |
|
38 |
|
39 <p>This is SunSpider, a JavaScript benchmark. This benchmark tests the |
|
40 core JavaScript language only, not the DOM or other browser APIs. It |
|
41 is designed to compare different versions of the same browser, and |
|
42 different browsers to each other. Unlike many widely available |
|
43 JavaScript benchmarks, this test is:</p> |
|
44 |
|
45 <dl> |
|
46 <dt>Real World<dt> |
|
47 <dd>This test mostly avoids microbenchmarks, and tries to focus on |
|
48 the kinds of actual problems developers solve with JavaScript today, |
|
49 and the problems they may want to tackle in the future as the language |
|
50 gets faster. This includes tests to generate a tagcloud from JSON |
|
51 input, a 3D raytracer, cryptography tests, code decompression, and |
|
52 many more examples. There are a few microbenchmarkish things, but they |
|
53 mostly represent real performance problems that developers have |
|
54 encountered.</dd> |
|
55 |
|
56 <dt>Balanced<dt> |
|
57 <dd>This test is balanced between different areas of the language and |
|
58 different types of code. It's not all math, all string processing, or |
|
59 all timing simple loops. In addition to having tests in many |
|
60 categories, the individual tests were balanced to take similar amounts |
|
61 of time on currently shipping versions of popular browsers.</dd> |
|
62 |
|
63 <dt>Statistically Sound<dt> |
|
64 <dd>One of the challenges of benchmarking is knowing how much noise |
|
65 you have in your measurements. This benchmark runs each test multiple |
|
66 times and determines an error range (technically, a 95% confidence |
|
67 interval). In addition, in comparison mode it tells you if you have |
|
68 enough data to determine if the difference is statistically |
|
69 significant.</dd> |

|
75 test cases five times and can take a minute or longer to complete.)</small></p> |
