For a given member function of the form void foo::f0(), passing this to boost bind results in the class instance being copied 7 times.

Storing the result of bind in boost function incurs another 11 copies

(code and results are here: http://boost.codepad.org/6jBmoKuj)

Using tr1::bind and function has slightly better results, but still not ideal: Doing just tr1::bind results in the class instance being copied 4 times.

Storing the result of bind in tr1 function incurs another 3 copies

(code and results are here: http://boost.codepad.org/w1EV6JBY)

Am I right in saying this is because boost::bind uses normal templates while tr1::bind uses variadic templates?

Either way this is not very efficient. Is there a way to improve this?
