I once hacked a quick benchmark to compare dispatch times of Bind&Function (1.34 versions) vs. FastDelegate.
With an inlineable replacement for 'boost::mem_fn' (accepting the member function pointer as a non-type template argument)
FastDelegate turned out to be (not quite) twice as fast as Function&Bind with MSVC, which isn't that much IMO held against the lost flexibility, such as not being able to use arbitrary function objects and only binding 'this'.
FastDelegate will always have faster invocation, because it optimizes for a very narrow set of cases. The invocation performance of Boost.Function won't have changed much from 1.33.x to 1.34.x. It's the copy performance that drastically improved. That part of the benchmark should be re-run with Boost 1.34.x. - Doug
