--- Performance numbers update for [openssl.org #3054] ---
Following the recent release of the 4th Generation Intel® Core™ processor
family, we provide performance numbers for the patch.
All measurements were carried out on an Core™ i7-4770K processor, running at
3.5 GHz, with Turbo boost and hyper-threading *disabled*.
For reference, we also provide the performance numbers for OpenSSL, on the 3rd
Generation Intel® Core™ i7-3770K, running at 3.5 GHz.
Remarks:
IVB – stands for performance on i7-3770K, for the latest git version of OpenSSL
OpenSSL – stands for performance on i7-4770K, for the latest git version of
OpenSSL
Patch – stands for performance on i7-4770K, for the latest git version of
OpenSSL, with our ModExp AVX2 patch applied
Speedup signifies the performance gain from the patch on i7-4770K.
