How to read jsben.ch benchmark result?

Question

I've compared three fibonacci algorithms with jsben.ch and as expected first one is the fastest (it even got a little award icon):

Yet, I can't find what the numbers next to code block result mean? The higher, the better but what's the unit?

Answer 1

我能想到的唯一合理的单位（这是我的假设）是结果显示ops/sec意味着每个测试在一秒内可以执行多少次。

然而，如果jsben.ch能清楚地说明这一点以避免混淆或至少在帮助部分解释其含义（遗憾的是也缺少），那就更好了。
