什么是C ++编译器为Windows生成最快的代码
XP专业版（32位）？我必须在这两者之间做出选择：
- Visual C ++ 2005编译器
- 适用于Windows的英特尔C ++编译器9.0
我之前使用这两个编译器的旧版本的经验告诉我，英特尔代码的运行速度比MS代码快。但是现在我即将升级，我会选择那个产生最快的
代码（事情可能已经改变了！）。
我以为你们中的一些人可能已经看过一些大型的b / b
C ++项目的基准测试，所以可以对此有所了解。
谢谢，
Ozo。
What would be the C++ compiler producing the fastest code for Windows
XP Pro (32-bit)? I have to choose between these two:
- Visual C++ 2005 compiler
- Intel C++ Compiler 9.0 for Windows
My previous experience with older versions of these two compilers told
me that Intel code was running faster than MS code. But now that I am
about to upgrade, I would lile to pick the one producing the fastest
code (things may have changed!).
I thought that some of you could have seen benchmarks with some large
C++ projects and so could shed some light on this.
Thanks,
Ozo.
推荐答案
这真的是最重要的事情吗？
Is that really the most important thing ?

是的。我正在开发一个实时应用程序，其中每个
毫秒都很重要。我更喜欢通过简单地升级编译器（然后使用这个额外的时间来做更多）来获得1-2毫秒而不是
重新设计应用程序的大部分内容希望得到相同的
结果。在实时系统中，进行实际处理的可用总数为b $ b $毫秒是有限的;如果一个更好的编译器
让你在同一时间做更多的事情，那就非常受欢迎了。

Yes it is. I am working on a real-time application where each
milisecond is important. I prefer to gain 1-2 ms by simply upgrading
the compiler (and then use this extra time to do more) instead of
re-designing large parts of the application hoping to get the same
result. In real-time systems, the total number of available
miliseconds to do actual processing is limited; If a better compiler
let you do more in the same time, it is more than welcome.

我不知道任何性能基准测试...
您是否考虑过（免费）GNU CGG系统（''gcc''' C，
和''g ++''用于C ++）？

I don''t know of any performance benchmarks...
Have you considered the (free) GNU CGG System (''gcc'' for C,
and ''g++'' for C++)?
