I know that move semantics is about more than improved performance, but am interested in that side of things, especially as the above compiler appears suboptimal in terms of copy elision and RVO. I am wondering for example whether are there any (compiler-specific) factors which could mitigate against the performance benefits of doing a move vs a copy of a vector, using these libraries, for example.

Hi,

unfortunately Boost.Move and Boost.Container are not working up to now 
on Sun c++ even on trunk (1.49). See 
http://www.boost.org/development/tests/trunk/developer/container.html.

Best,
