-# ====================================================================
-# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
-# project. The module is, however, dual licensed under OpenSSL and
-# CRYPTOGAMS licenses depending on where you obtain it. For further
-# details see http://www.openssl.org/~appro/cryptogams/.
-# ====================================================================

-# December 2007

-# The reason for undertaken effort is basically following. Even though
-# Power 6 CPU operates at incredible 4.7GHz clock frequency, its PKI
-# performance was observed to be less than impressive, essentially as
-# fast as 1.8GHz PPC970, or 2.6 times(!) slower than one would hope.
-# Well, it's not surprising that IBM had to make some sacrifices to
-# boost the clock frequency that much, but no overall improvement?
-# Having observed how much difference did switching to FPU make on
-# UltraSPARC, playing same stunt on Power 6 appeared appropriate...
-# Unfortunately the resulting performance improvement is not as
-# impressive, ~30%, and in absolute terms is still very far from what
-# one would expect from 4.7GHz CPU. There is a chance that I'm doing
-# something wrong, but in the lack of assembler level micro-profiling
-# data or at least decent platform guide I can't tell... Or better
-# results might be achieved with VMX... Anyway, this module provides
-# *worse* performance on other PowerPC implementations, ~40-15% slower
-# on PPC970 depending on key length and ~40% slower on Power 5 for all
-# key lengths. As it's obviously inappropriate as "best all-round"
-# alternative, it has to be complemented with run-time CPU family
-# detection. Oh! It should also be noted that unlike other PowerPC
-# implementation IALU ppc-mont.pl module performs *suboptimaly* on
-# >=1024-bit key lengths on Power 6. It should also be noted that
-# *everything* said so far applies to 64-bit builds! As far as 32-bit
-# application executed on 64-bit CPU goes, this module is likely to
-# become preferred choice, because it's easy to adapt it for such
-# case and *is* faster than 32-bit ppc-mont.pl on *all* processors.
-
-# February 2008
-
-# Micro-profiling assisted optimization results in ~15% improvement
-# over original ppc64-mont.pl version, or overall ~50% improvement
-# over ppc.pl module on Power 6. If compared to ppc-mont.pl on same
-# Power 6 CPU, this module is 5-150% faster depending on key length,
-# [hereafter] more for longer keys. But if compared to ppc-mont.pl
-# on 1.8GHz PPC970, it's only 5-55% faster. Still far from impressive
-# in absolute terms, but it's apparently the way Power 6 is...
