You're right but make remains the same: 1) new: shared_ptr: 21234066 ns make: shared_ptr: 18122766 ns
2) make: shared_ptr: 18271141 ns new: shared_ptr: 13395539 ns
That's not what I see on my machine: $ ./a.out new: shared_ptr: 15096947 ns make: shared_ptr: 10986592 ns # recompile with different order $ ./a.out make: shared_ptr: 14187251 ns new: shared_ptr: 11498070 ns My cpu cores turn down their clock frequency when idle to save power, and I don't know how long it takes to switch speeds. Maybe the cpu clock speed is jumping from low to high speed while the benchmark is running. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iEYEARECAAYFAk3fpk0ACgkQ5vihyNWuA4V/BwCggGtUFvMgSOYdNtFgmQDeU8RU aD0AnRRMZfgr0qXZREuDnFoVNbqTmDAU =uPv7 -----END PGP SIGNATURE-----
