"Almost" refers to the fact that AES_cbc_encrypt 18# doesn't handle partial vectors (doesn't have to if called from 19# EVP only). "Drop-in" implies that this module doesn't share key 20# schedule structure with the original nor does it make assumption 21# about its alignment... 22# 23# Performance summary. aes-x86_64.pl column lists large-block CBC 24# encrypt/decrypt/with-hyper-threading-off(*) results in cycles per 25# byte processed with 128-bit key, and vpaes-x86_64.pl column - 26# [also large-block CBC] encrypt/decrypt. 27# 28# aes-x86_64.pl vpaes-x86_64.pl 29# 30# Core 2(**) 30.5/43.7/14.3 21.8/25.7(***) 31# Nehalem 30.5/42.2/14.6 9.8/11.8 32# Atom 63.9/79.0/32.1 64.0/84.8(***) 33# 34# (*) "Hyper-threading" in the context refers rather to cache shared 35# among multiple cores, than to specifically Intel HTT.
