With such a hefty and obnoxious signature, this is my response.

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? ------------------------------ This message w/attachments (message) is intended solely for the use of the intended recipient(s) and may contain information that is privileged, confidential or proprietary.
