Not really useful in this discussion, but Visual Studio Express 2008 doesn't have the optimizing C++ compiler that is available in the higher Visual Studio versions. In debug builds on VC++ some additional checks are enabled which will slow things down, but the optimizing compiler (which *is* available in the free to download platform SDK) will improve performance more than just disabling of the debug checks.
