-# 2.22x RC4 tune-up:-) It should be noted though that my hand [as in |
-# "hand-coded assembler"] doesn't stand for the whole improvement |
-# coefficient. It turned out that eliminating RC4_CHAR from config |
-# line results in ~40% improvement (yes, even for C implementation). |
-# Presumably it has everything to do with AMD cache architecture and |
-# RAW or whatever penalties. Once again! The module *requires* config |
-# line *without* RC4_CHAR! As for coding "secret," I bet on partial |
-# register arithmetics. For example instead of 'inc %r8; and $255,%r8' |
-# I simply 'inc %r8b'. Even though optimization manual discourages |
-# to operate on partial registers, it turned out to be the best bet. |
-# At least for AMD... How IA32E would perform remains to be seen... |
- |
-# November 2004 |
-# |
-# As was shown by Marc Bevand reordering of couple of load operations |
-# results in even higher performance gain of 3.3x:-) At least on |
-# Opteron... For reference, 1x in this case is RC4_CHAR C-code |
-# compiled with gcc 3.3.2, which performs at ~54MBps per 1GHz clock. |
-# Latter means that if you want to *estimate* what to expect from |
-# *your* Opteron, then multiply 54 by 3.3 and clock frequency in GHz. |
- |
-# November 2004 |

-# Intel P4 EM64T core was found to run the AMD64 code really slow... |
-# The only way to achieve comparable performance on P4 was to keep |
-# RC4_CHAR. Kind of ironic, huh? As it's apparently impossible to |
-# compose blended code, which would perform even within 30% marginal |
-# on either AMD and Intel platforms, I implement both cases. See |
-# rc4_skey.c for further details... |
- |
-# April 2005 |
-# |
-# P4 EM64T core appears to be "allergic" to 64-bit inc/dec. Replacing |
-# those with add/sub results in 50% performance improvement of folded |
-# loop... |
- |
-# May 2005 |
-# |
-# As was shown by Zou Nanhai loop unrolling can improve Intel EM64T |
-# performance by >30% [unlike P4 32-bit case that is]. But this is |
-# provided that loads are reordered even more aggressively! Both code |
-# pathes, AMD64 and EM64T, reorder loads in essentially same manner |
-# as my IA-64 implementation. On Opteron this resulted in modest 5% |
-# improvement [I had to test it], while final Intel P4 performance |
-# achieves respectful 432MBps on 2.8GHz processor now. For reference. |
-# If executed on Xeon, current RC4_CHAR code-path is 2.7x faster than |
-# RC4_INT code-path. While if executed on Opteron, it's only 25% |
-# slower than the RC4_INT one [meaning that if CPU µ-arch detection |
-# is not implemented, then this final RC4_CHAR code-path should be |
-# preferred, as it provides better *all-round* performance]. |
- |
-# March 2007 |
-# |
-# Intel Core2 was observed to perform poorly on both code paths:-( It |
-# apparently suffers from some kind of partial register stall, which |
-# occurs in 64-bit mode only [as virtually identical 32-bit loop was |
-# observed to outperform 64-bit one by almost 50%]. Adding two movzb to |
-# cloop1 boosts its performance by 80%! This loop appears to be optimal |
-# fit for Core2 and therefore the code was modified to skip cloop8 on |
-# this CPU. |
- |
-# May 2010 |
-# |
-# Intel Westmere was observed to perform suboptimally. Adding yet |
-# another movzb to cloop1 improved performance by almost 50%! Core2 |
-# performance is improved too, but nominally... |
- |
-# May 2011 |
-# |
-# The only code path that was not modified is P4-specific one. Non-P4 |
-# Intel code path optimization is heavily based on submission by Maxim |
-# Perminov, Maxim Locktyukhin and Jim Guilford of Intel. I've used |
-# some of the ideas even in attempt to optmize the original RC4_INT |
-# code path... Current performance in cycles per processed byte (less |
-# is better) and improvement coefficients relative to previous |
-# version of this module are: |
-# |
-# Opteron 5.3/+0%(*) |
-# P4 6.5 |
-# Core2 6.2/+15%(**) |
-# Westmere 4.2/+60% |
-# Sandy Bridge 4.2/+120% |
-# Atom 9.3/+80% |
-# |
-# (*) But corresponding loop has less instructions, which should have |
-# positive effect on upcoming Bulldozer, which has one less ALU. |
-# For reference, Intel code runs at 6.8 cpb rate on Opteron. |
-# (**) Note that Core2 result is ~15% lower than corresponding result |
-# for 32-bit code, meaning that it's possible to improve it, |
-# but more than likely at the cost of the others (see rc4-586.pl |
-# to get the idea)... |
