This is a patched version of zlib modified to use
Pentium-optimized assembly code in the deflation algorithm. The files
changed/added by this patch are:
README.586
match.S
The effectiveness of these modifications is a bit marginal, as the the
program's bottleneck seems to be mostly L1-cache contention, for which
there is no real way to work around without rewriting the basic
algorithm. The speedup on average is around 5-10% (which is generally
less than the amount of variance between subsequent executions).
However, when used at level 9 compression, the cache contention can
drop enough for the assembly version to achieve 10-20% speedup (and
sometimes more, depending on the amount of overall redundancy in the
files). Even here, though, cache contention can still be the limiting
factor, depending on the nature of the program using the zlib library.
This may also mean that better improvements will be seen on a Pentium
with MMX, which suffers much less from L1-cache contention, but I have
not yet verified this.
Note that this code has been tailored for the Pentium in particular,
and will not perform well on the Pentium Pro (due to the use of a
partial register in the inner loop).
If you are using an assembler other than GNU as, you will have to
translate match.S to use your assembler's syntax. (Have fun.)

Added for zlib 1.1.3:
The patches come from
http://www.muppetlabs.com/~breadbox/software/assembly.html
To compile zlib with this asm file, copy match.S to the zlib directory
then do:
CFLAGS="-O3 -DASMV" ./configure

*
* Two optimization notes on the choice of instructions:
*
* The first instruction uses a 16-bit address, which costs an extra,
* unpairable cycle. This is cheaper than doing a 32-bit access and
* zeroing the high word, due to the 3-cycle misalignment penalty which
* would occur half the time. This also turns out to be cheaper than
* doing two separate 8-bit accesses, as the memory is so rarely in the
* L1 cache.
*
* The window buffer, however, apparently spends a lot of time in the
* cache, and so it is faster to retrieve the word at the end of the
* match string with two 8-bit loads. The instructions that test the
* word at the beginning of the match string, however, are executed
* much less frequently, and there it was cheaper to use 16-bit
* instructions, which avoided the necessity of saving off and
* subsequently reloading one of the other registers.

Update:
I've been ignoring these assembly routines for years, believing that
gcc's generated code had caught up with it sometime around gcc 2.95
and the major rearchitecting of the Pentium 4. However, I recently
learned that, despite what I believed, this code still has some life
in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
faster than the code produced by gcc 4.1.
In acknowledgement of its continuing usefulness, I've altered the
license to match that of the rest of zlib. Share and Enjoy!

; gvmat32.asm -- Asm portion of the optimized longest_match for 32 bits x86
; Copyright (C) 1995-1996 Jean-loup Gailly and Gilles Vollant.
; File written by Gilles Vollant, by modifiying the longest_match
; from Jean-loup Gailly in deflate.c
;
; http://www.zlib.net
; http://www.winimage.com/zLibDll
; http://www.muppetlabs.com/~breadbox/software/assembly.html
;
; For Visual C++ 4.x and higher and ML 6.x and higher
; ml.exe is in directory \MASM611C of Win95 DDK
; ml.exe is also distributed in http://www.masm32.com/masmdl.htm
; and in VC++2003 toolkit at http://msdn.microsoft.com/visualc/vctoolkit2003/
;
; this file contain two implementation of longest_match
;
; longest_match_7fff : written 1996 by Gilles Vollant optimized for
; first Pentium. Assume s->w_mask == 0x7fff
; longest_match_686 : written by Brian raiter (1998), optimized for Pentium Pro
;
; for using an seembly version of longest_match, you need define ASMV in project
; There is two way in using gvmat32.asm
;
; A) Suggested method
; if you want include both longest_match_7fff and longest_match_686
; compile the asm file running
; ml /coff /Zi /Flgvmat32.lst /c gvmat32.asm
; and include gvmat32c.c in your project
; if you have an old cpu (386,486 or first Pentium) and s->w_mask==0x7fff,
; longest_match_7fff will be used
; if you have a more modern CPU (Pentium Pro, II and higher)
; longest_match_686 will be used
; on old cpu with s->w_mask!=0x7fff, longest_match_686 will be used,
; but this is not a sitation you'll find often
;
; B) Alternative
; if you are not interresed in old cpu performance and want the smaller
; binaries possible
;
; compile the asm file running
; ml /coff /Zi /c /Flgvmat32.lst /DNOOLDPENTIUMCODE gvmat32.asm
; and do not include gvmat32c.c in your project (ou define also
; NOOLDPENTIUMCODE)
;
; note : as I known, longest_match_686 is very faster than longest_match_7fff
; on pentium Pro/II/III, faster (but less) in P4, but it seem
; longest_match_7fff can be faster (very very litte) on AMD Athlon64/K8
;

; this file contain two implementation of longest_match
;
; this longest_match was written by Brian raiter (1998), optimized for Pentium Pro
; (and the faster known version of match_init on modern Core 2 Duo and AMD Phenom)
;
; for using an assembly version of longest_match, you need define ASMV in project
;
; compile the asm file running
; ml /coff /Zi /c /Flmatch686.lst match686.asm
; and do not include match686.obj in your project
;
; note: contrib of zLib 1.2.3 and earlier contained both a deprecated version for
; Pentium (prior Pentium Pro) and this version for Pentium Pro and modern processor
; with autoselect (with cpu detection code)
; if you want support the old pentium optimization, you can still use these version
;
; this file is not optimized for old pentium, but it compatible with all x86 32 bits
; processor (starting 80386)
