Does this slowdown happen in release mode? If yes, did you #define
_SCL_SECURE=0 before including anything else? The STL for VC9 is known to be
slow in release mode if the 'secure' implementation is used (which
unfortunately is the default). You have to be very careful with this,
though, as it breaks ABI compatibility. That means you should use the same
settings for _SCL_SECURE for _all_ modules used in your application.
Otherwise strange errors will happen at runtime.
