Any thoughts?
There is no difference between
block_ptr<T> a = make_block<T>(whatever); and block_ptr<T> a(new block<T>(whatever));
Your temporaries in question are removed by NRVO.
That's right, with the optimization flags turned on I get: 0.116u 0.004s 0:00.12 91.6%
(This is block_ptr_test3 BTW)
Sorry operator new is still faster with optimization flags turned on: time of new block (O3): 0.044u 0.040s 0:00.09 88.8% time of make_block (O3): 0.116u 0.004s 0:00.12 91.6% -Phil
