Hey, I’m the creator of jsPerf.
- The fastest test(s) get a green background. The slowest test(s) get a pink/red background.
- See below.
- It means the test can run about 95,814,583 times a second.
- ± 1.95 is the margin of error. (For more info, see below.)
- “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?

@Raynos: “jsPerf” is one of my saved searches on Twitter. A bot auto-tweeted a link to this question, so I answered it :)

@MathiasBynens How should I intepret the results when
Infinity ±0.00% fastest appears?
