为什么V8节点。JS比我的c++addon要快?-WhyV8inNode.JSisfasterthaninmynativeC++addon?

Why Google's V8 Javascript engine in my C++ addon works significantly slower than in Node.JS?

为什么谷歌在我的c++ addon中使用的V8 Javascript引擎要比Node.JS中慢得多?

I've tried to write some stupidly simple code for generating prime numbers in the Javascript and ran it in V8 via my C++ addon and directly in Node.JS.

我尝试编写一些愚蠢的简单代码，用于在Javascript中生成质数，并在V8中通过我的c++ addon和Node.JS直接运行它。

I was quite shocked, because both should be using the same Javascript engine and both have executed the same code (time in milliseconds, less is better):

我非常震惊，因为两者都应该使用相同的Javascript引擎，并且都执行了相同的代码(时间单位为毫秒，越少越好):

V8 in Node.JS:  495517
V8 in Node.JS C++ Addon:  623598

Here is the source of Javascript module and source of C++ addon that runs same Javascript code (and I think problem not in the interop, because measuring of time works directly in JS):

这是Javascript模块的源代码和c++ addon的源代码，它运行相同的Javascript代码(我认为在内部操作中没有问题，因为时间度量直接在JS中工作):
