# aes-*-cbc benchmarks are improved by >70% [compared to gcc 3.3.2 on
# Opteron 240 CPU] plus all the bells-n-whistles from 32-bit version
# [you'll notice a lot of resemblance], such as compressed S-boxes
# in little-endian byte order, prefetch of these tables in CBC mode,
# as well as avoiding L1 cache aliasing between stack frame and key
-# schedule and already mentioned tables.
+# schedule and already mentioned tables, compressed Td4...

# Performance in number of cycles per processed byte for 128-bit key:
#
-# ECB CBC encrypt
-# AMD64 13.7 13.0(*)
-# EM64T 20.2 18.6(*)
+# ECB encrypt ECB decrypt CBC large chunk
+# AMD64 33 41 13.0
+# EM64T 38 59 18.6(*)
+# Core 2 30 43 14.5(*)
#
-# (*) CBC benchmarks are better than ECB thanks to custom ABI used
-# by the private block encryption function.
