Comparison of computing time in Linux and xp

I have heard that the computing efficiency in Linux is high, so many large programs are generally used in Linux. Recently, I also specifically used a small program to compare the efficiency of the two. My Linux is Fedora9, which is a relatively new Linux version and can be automatically mounted to the xp hard disk. I used the man command to view the compilation of g ++ and c ++, which means that c ++ files can be compiled smoothly. I used VC6 compilation in xp. This is a product of Microsoft and is very good for writing application software.

My Linux is Fedora 9, which is a relatively new Linux version and can be automatically mounted to the xp hard disk. I used the man command to view the compilation of g ++ and c ++, which means that c ++ files can be compiled smoothly.

I used VC6 compilation in xp, a product of Microsoft. It is very useful for writing application software, but it is average for numerical computing, but I am not quite sure which compiler has a good compilation for the value. vc6 is generally used.

I wrote a small program in which there is a simple cyclic superposition of 10000000. I used int and double types for experiments respectively. I found that these two types of computing in Linux are very efficient. The computing time for Linux and xp is about, which is not a decimal number. It seems that the computing efficiency of Linux is high! But I just implemented a for loop. I didn't use other complicated programs. Maybe they are similar in terms of application software?
