Here the vdrift trunk profile(MinGW GCC4.4.3):

Code:

  1.59     42.56     1.11                             std::string::append(std::string const&)

  1.46     43.58     1.02                             std::string::_Rep::_M_clone(std::allocator<char> const&, unsigned int)

  1.20     44.42     0.84                             std::string::reserve(unsigned int)

And I get similar results on my intel machine. So I guess it has to be OS or compiler related.
