解释这个JsPerf.com结果 [英] Explain this JsPerf.com result

问题描述

我在这个网站上进行了测试
以获得以下详细解释：

• 什么是ops / sec？


• 它会进行多少次迭代？


• 根据什么计算哪个更快？


• 这些计算背后的公式是什么？

I ran a test on this website http://jsperf.com/

I want some one to explain

1. What does green and pink signifies
2. What is ops per second
3. what is 95,814,583
4. what is +- 1.95% is
5. whats does 'fastest' and 'slower' means

解决方案

Hey, I’m the creator of jsPerf.

1. The fastest test(s) get a green background. The slowest test(s) get a pink/red background.
2. See below.
3. It means the test can run about 95,814,583 times a second.
4. ± 1.95 is the margin of error. (For more info, see below.)
5. "fastest" means this is the fastest test in the test case. 19% slower means this test is 19% slower than the fastest test in the test case.

See John-David Dalton’s answer to "How does jsPerf work?" for a detailed explanation of the following:

• What is "ops/sec"?
• How many iterations does it do?
• On what basis does it calculate which is faster?
• What is the formula behind these calculations?
