### AES-128 [originally in CTR mode] ###
# Emilia's this(*) difference
#
# Core 2 9.30 8.69 +7%
-# Nehalem(**) 7.63 6.98 +9%
-# Atom 17.1 17.4 -2%(***)
+# Nehalem(**) 7.63 6.88 +11%
+# Atom 17.1 16.4 +4%
+# Silvermont - 12.9
+# Goldmont - 8.85
#
# (*) Comparison is not completely fair, because "this" is ECB,
# i.e. no extra processing such as counter values calculation
# (**) Results were collected on Westmere, which is considered to
# be equivalent to Nehalem for this code.
#
-# (***) Slowdown on Atom is rather strange per se, because original
-# implementation has a number of 9+-bytes instructions, which
-# are bad for Atom front-end, and which I eliminated completely.
-# In attempt to address deterioration sbox() was tested in FP
-# SIMD "domain" (movaps instead of movdqa, xorps instead of
-# pxor, etc.). While it resulted in nominal 4% improvement on
-# Atom, it hurted Westmere by more than 2x factor.
-#
# As for key schedule conversion subroutine. Interface to OpenSSL
# relies on per-invocation on-the-fly conversion. This naturally
# has impact on performance, especially for short inputs. Conversion
# function is:
#
# conversion conversion/8x block
-# Core 2 410 0.37
-# Nehalem 310 0.35
-# Atom 570 0.26
+# Core 2 240 0.22
+# Nehalem 180 0.20
+# Atom 430 0.20
#
# The ratio values mean that 128-byte blocks will be processed
-# 21-27% slower, 256-byte blocks - 12-16%, 384-byte blocks - 8-11%,
+# 16-18% slower, 256-byte blocks - 9-10%, 384-byte blocks - 6-7%,
# etc. Then keep in mind that input sizes not divisible by 128 are
# *effectively* slower, especially shortest ones, e.g. consecutive
# 144-byte blocks are processed 44% slower than one would expect,
# Add decryption procedure. Performance in CPU cycles spent to decrypt
# one byte out of 4096-byte buffer with 128-bit key is:
#
-# Core 2 11.0
-# Nehalem 9.16
+# Core 2 9.98
+# Nehalem 7.80
+# Atom 17.9
+# Silvermont 14.0
+# Goldmont 10.2
