* "ops/sec" stands for operations per second. That is how many times a test is projected to execute in a second. | * "ops/sec" stands for operations per second. That is how many times a test is projected to execute in a second. | ||
* A test is repeatedly executed until it reaches the minimum time needed to get a percentage uncertainty for the measurement of less than or equal to 1%. The number of iterations will vary depending on the resolution of the environment’s timer and how many times a test can execute in the minimum run time. We collect completed test runs for 5 seconds (configurable), or at least 5 runs (also configurable), and then perform statistical analysis on the sample. So, a test may be repeated 100,000 times in 50 ms (the minimum run time for most environments), and then repeated 100 times more (5 seconds). A larger sample size (in this example, 100), leads to a smaller margin of error. | * A test is repeatedly executed until it reaches the minimum time needed to get a percentage uncertainty for the measurement of less than or equal to 1%.

* benchmark.js returns ops/sec, rounded to hundredths. This number was inverted to obtain secs/op, losing precision in the process. | |||
