Page 5: Overview
OpenSSL. The hashing and private key encryption can be implemented using the multi- buffer technique described in [4] for best performance on Intel processors. There are two basic ways that processing multiple buffers in parallel can improve performance: processing the buffers with SIMD instructions or processing multiple buffers in parallel to reduce data dependency limits. -

Core™ i5-650 processor at a frequency of 3.20 GHz, based on Intel® microarchitecture code named Westmere • Intel® Core™ i7-2600 processor at a frequency of 3.40 GHz, based on Generation Intel® Core™ processor family The fact that the two processors have different clock frequencies does not affect the comparison, as we have normalized the performance results to cycles. -

AES128-CBC-Encrypt 1.52 0.83 1.83 In all cases, we observe a large performance boost with the Intel® Core™ i7- 2600 processor based on the Generation Intel® Core™ processor family, with gains ranging from 1.15-1.83X. The absolute performance is very impressive as well, with 0.83 cycles/byte for AES128 and 2.2 cycles/byte for SHA1. -
