Most of the configuration on Windows will be the same as for different platforms. The MPM used on windows is different to that used on Unix/Linux systems so that is where most of the differences will be. Modules that depend on external resources e.g. PHP will be installed and configured differently on windows.

As for performance I don't have a lot of information on that front. Best way to check this is to run some benchmark tests to see if performance on windows is acceptable.

Normally they are the same, but devices and directories name are not in same and in different places
