I just tested it using make_shared & make_block and I get:
auto_ptr: 11109841 ns
shared_ptr: 21215277 ns
block_ptr: 143637475 ns
auto_ptr 4583447 ns
shared_ptr: 10675000 ns
block_ptr: 67152785 ns
FYI make_shared is slower than new because of the temporary it creates.
If people what speed they should stick to operator new in all cases.
