Subject: Re: JtR compilation warnings on OS X 10.7.3 with Xcode 4.3.2
Here is some strange results. I ran the same compiled applications on a 10.6 system (3.2 Ghz core i7 cpu) and there was a significant slow-down in some cases. See below:
OpenSSL Version:
./john_single -test -format:episerver
Benchmarking: EPiServer [32/64]... DONE
Raw: 4850K c/s real, 4850K c/s virtual
./john_single -test -format:drupal7
Benchmarking: Drupal 7 $S$ (SHA-512 x 16385) [64/64]... DONE
Raw: 98.0 c/s real, 98.0 c/s virtual
CommonCrypto Version:
./john_single -test -format:episerver
Benchmarking: EPiServer [32/64]... DONE
Raw: 4153K c/s real, 4153K c/s virtual
./john_single -test -format:drupal7
Benchmarking: Drupal 7 $S$ (SHA-512 x 16385) [64/64]... DONE
Raw: 88.0 c/s real, 88.0 c/s virtual
On a 3.6 Ghz core i5 system running 10.7.3, I get the expected speed up:
OpenSSL Version:
./john_single -test -format:episerver
Benchmarking: EPiServer [32/64]... DONE
Raw: 4329K c/s real, 4373K c/s virtual
./john_single -test -format:drupal7
Benchmarking: Drupal 7 $S$ (SHA-512 x 16385) [64/64]... DONE
Raw: 89.1 c/s real, 89.1 c/s virtual
CommonCrypto Version:
./john_single -test -format:episerver
Benchmarking: EPiServer [32/64]... DONE
Raw: 5521K c/s real, 5577K c/s virtual
./john_single -test -format:drupal7
Benchmarking: Drupal 7 $S$ (SHA-512 x 16385) [64/64]... DONE
Raw: 102 c/s real, 102 c/s virtual
So maybe this is why we get the compile alerts in Lion and not Snow Leopard. Apple must have made significant improvements to the CommonCrypto code.
