I can't see how it would affect performance, but the real answer you
will get from performance tests.

boost::array<char, 1> buff_;// member
//...
socket_.async_receive(boost::asio::buffer(buff), handler);
//...
When the handler() is called, buff_ can't contain more that 1 byte, as
its size is 1 byte.

Of course, you can supply asio::streambuf as a buffer. It's built on
top of std::vector, and it auto-resizes as needed during data
receiving. See asio examples for details. (Eg.,
http://www.boost.org/doc/libs/1_38_0/doc/html/boost_asio/example/http/client/async_client.cpp)
