+# 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, 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(*)
+#
+# (*) CBC benchmarks are better than ECB thanks to custom ABI used
+# by the private block encryption function.
+
+$verticalspin=1; # unlike 32-bit version $verticalspin performs
