Netty数据流性能+ websocket性能(Netty data streaming performance + websocket performance)

 我想查看netty的一些特定性能数字，并查看netty网站上相关文章部分中的各个链接。  
 但是大多数人都谈到了与网络服务器同时连接的数量，而不是关于数据传输速率或类似的东西 ，我希望看一下。  
 此外，任何特定于netty websocket服务器的性能数字？ （据我所知，它可能在某种程度上依赖于websocket协议，是吗？）  
 如果有人做了一些工作/在网络上看到了两个领域中的任何一个，他们可以分享一些数据/见解吗？ 

I wanted to look at some particular performance numbers for netty and have looked over the various links in the related articles section on the netty website. 
But most of them talk about the number of simultaneous connections to a netty server and not about the data transfer rate or something similar which I wish to look over. 
Also , any performance numbers specifically for a netty websocket server ? (I understand it may depend on the websocket protocol used as well to some extent , is it ?)  
If someone has done some work / seen some links on the web in any of the 2 areas , could they please share some data numbers / insights ?

 你正在寻找的是一个功能模板和可变参数模板（a / k / a参数包） ：  
template<class ... Args>
void f(Args ... args)
{
    std::cout << sizeof...(args) << "\n";
}

int main()
{
    f(0, 1, 2); // prints 3
    f(0, 1, 2, 3, 4); // prints 5
}
 
 这通常不是您默认使用的。 考虑使用范围：  
template<class Iterator>
void f(Iterator begin, Iterator end)
{
    std::cout << std::distance(begin, end) << "\n";
}
 
 这更具惯用性。 

What you're looking for is a function-template in conjunction with variadic templates (a/k/a parameter packs): 
template<class ... Args>
void f(Args ... args)
{
    std::cout << sizeof...(args) << "\n";
}

int main()
{
    f(0, 1, 2); // prints 3
    f(0, 1, 2, 3, 4); // prints 5
}
 
This is generally not what you would use by default. Consider using ranges: 
template<class Iterator>
void f(Iterator begin, Iterator end)
{
    std::cout << std::distance(begin, end) << "\n";
}
 
which is more idiomatic.
