I already tried to use Boost.Coroutine but the overhead is very high. Now, I would like to perform an evaluation of two approaches, seems that the use of Boost.Context (without coroutines) is faster.

The documented signature of make_fcontext() accepts a classic C
function pointer:
http://www.boost.org/doc/libs/1_56_0/libs/context/doc/html/context/context/boost_fcontext.htmlboost::bind() does not produce a classic C function pointer.
Boost.Context is a very low-level library, with distinct
platform-specific assembler implementations for various combinations
of OS and hardware. Boost.Coroutine is a more C++-level API built on
Boost.Context, and Coroutine almost certainly what you should be using
unless your requirements are pretty unusual.
