Linux faster than Windows?
I'm writting a C++ console application. Basic input output ... with <fstream>
If take the idential code and run it on Linux(RedHat) g++ vs Windows (XP) Visual C++ 2005, which is faster? Why?

That's a loaded question. I mean, you've got more than just the os to deal with. The type of processor, memory, number of running programs, compiler version, etc will all determine the speed.
YOU say, which is faster and I say WHY :-)

It depends also on the linux system. I would say if you run it on gentoo. with no X no other services,
It would run faster in gentoo (gentoo optimize your Linux to your computer). But for file input output you wont
perceive a difference, since this operation can be done in a i386 in the same manner. It is basically a question if dma is on or not (direct access memory, it means that the harddisk will copy without any processor operation the data on the harddisk into the memory). It depends also with you use a usb disk. In linux you can say dont synchronize, so it will be 1000 times fastr, since it writes on the memory, and only if there is not enough memory or you umount the usb disk the file will be copied to the usb, only then. Windows normally copy at the very moment.
