I just noticed that if I do not define the BOOST_DISABLE_THREADS macro, 
root_ptr is faster than allocate_shared_noinit by 124%:

unique_ptr (new): 42.1397
unique_ptr (make_unique): 43.4631
shared_ptr (new): 76.4543
shared_ptr (make_shared): 76.6611
shared_ptr (allocate_shared_noinit): 81.9926
root_ptr (new): 66.3417

Thanks,
