+# September 2011.
+#
+# Port vpaes-x86_64.pl as 32-bit "almost" drop-in replacement for
+# aes-586.pl. "Almost" refers to the fact that AES_cbc_encrypt
+# doesn't handle partial vectors (doesn't have to if called from
+# EVP only). "Drop-in" implies that this module doesn't share key
+# schedule structure with the original nor does it make assumption
+# about its alignment...
+#
+# Performance summary. aes-586.pl column lists large-block CBC
+# encrypt/decrypt/with-hyper-threading-off(*) results in cycles per
+# byte processed with 128-bit key, and vpaes-x86.pl column - [also
+# large-block CBC] encrypt/decrypt.
+#
+# aes-586.pl vpaes-x86.pl
+#
+# Core 2(**) 28.1/41.4/18.3 21.9/25.2(***)
+# Nehalem 27.9/40.4/18.1 10.2/11.9
+# Atom 70.7/92.1/60.1 61.1/75.4(***)
+# Silvermont 45.4/62.9/24.1 49.2/61.1(***)
+#
+# (*) "Hyper-threading" in the context refers rather to cache shared
+# among multiple cores, than to specifically Intel HTT. As vast
+# majority of contemporary cores share cache, slower code path
+# is common place. In other words "with-hyper-threading-off"
+# results are presented mostly for reference purposes.
+#
+# (**) "Core 2" refers to initial 65nm design, a.k.a. Conroe.
+#
+# (***) Less impressive improvement on Core 2 and Atom is due to slow
+# pshufb, yet it's respectable +28%/64% improvement on Core 2
+# and +15% on Atom (as implied, over "hyper-threading-safe"
+# code path).
