"Almost" refers to the fact that AES_cbc_encrypt 25# doesn't handle partial vectors (doesn't have to if called from 26# EVP only). "Drop-in" implies that this module doesn't share key 27# schedule structure with the original nor does it make assumption 28# about its alignment... 29# 30# Performance summary. aes-x86_64.pl column lists large-block CBC 31# encrypt/decrypt/with-hyper-threading-off(*) results in cycles per 32# byte processed with 128-bit key, and vpaes-x86_64.pl column - 33# [also large-block CBC] encrypt/decrypt. 34# 35# aes-x86_64.pl vpaes-x86_64.pl 36# 37# Core 2(**) 29.6/41.1/14.3 21.9/25.2(***) 38# Nehalem 29.6/40.3/14.6 10.0/11.8 39# Atom 57.3/74.2/32.1 60.9/77.2(***) 40# Silvermont 52.7/64.0/19.5 48.8/60.8(***) 41# Goldmont 38.9/49.0/17.8 10.6/12.6 42# 43# (*) "Hyper-threading" in the context refers rather to cache shared 44# among multiple cores, than to specifically Intel HTT.
