EDIT: Turns out LZ4 0.9 is way faster then LZO, Thanks to Wonko.



===============================================================================
I'm having hard time finding Binaries for LZO 2.06 (can't even find older 2.xx versions). If something is GNU it should have binaries somewhere right? :confused1:

Broken Google takes me to:
01. http://www.oberhumer...e/lzo/#download
02. http://www.lzop.de/
03. http://www.lzop.de/download/lzop.htm

:huh: I found 1.xx version (http://www.lzop.org/) but... something very weird:
This one talks about 2.05 http://www.oberhumer.com/
This one talks about 2.06 http://www.oberhumer...opensource/lzo/
and This one talks about 3.00 (which is NOT open) http://www.oberhumer...ional/showcase/


Is it possible that author decided to not compile the binaries of 2.xx and also stop others? :mellow: and then close source? :huh:
I got this file "lzo-2.06.tar.gz" how do i make EXE out of this? :dubbio: I'm so used to cooked foods... :beer:


EDIT: Now THIS one says 1.xx is 2.xx?? http://www.lzop.org/lzop_news.php (second * bulleted line in changes) (EDIT3: but this is old 2005, binary mirrors coming soon etc means?)

EDIT2: Some information from one of those pages...
Key Facts
  • LZO is a portable lossless data compression library written in ANSI C.
  • Reliable and thoroughly tested. High adoption - each second terrabytes of data are compressed by LZO. No bugs since the first release back in 1996.
  • Offers pretty fast compression and *extremely* fast decompression.
  • Implements the fastest compression and decompression algorithms around. See the ratings for lzop in the famous Archive Comparison Test .
  • Includes slower compression levels achieving a quite competitive compression ratio while still decompressing at this very high speed.
  • Distributed under the terms of the GNU General Public License (GPL v2+).
  • Military-grade stability and robustness.

The last Stable Binary source shows here http://www.lzop.de/download/source/ :lightbulb:

Even GPL version looks fast enough...

Not at all.

The idea is Open Source, NOT "here, kid, get a compiled .exe besides the Source Code".

Some nice Open Source guys are so nice as to also provide a compiled build, but a lot of them don't.

Most of the latter peeps won't given you even a hint about HOW to compile the app, the Author in this case was kind enough to provide pre-made batches for most compilers/environments, see 00README.TXT.

I never managed to understand the reason for this form of "sadism" the otherwise good guys tend to indulge into, since they took a few hours/days/weeks/months/years to configure properly a complier and learn to use it then everyone should suffer the same pain :ph34r: :w00t: I really don't get it! :dubbio:

Unless you get a C compiler you are bound to live out of the "charity" of some other nice guys :worship: that may (or may not :() publish a compiled version.

Here is one:

Key Facts

But in this particular case, it is a GOOD thing that there is no pre-compiled version. :thumbsup:
WHAT the HECK do you need/want a library for if you are not a programmer? :hyper: :whistling:

If you need an application, or better, a Program ;), then use LZOP:
http://www.oberhumer...ource/lzo/#lzop
http://www.lzop.org/

LZOP versions are not directly connected to the LZO version AFAICU.

Yes I got that... thats why posted second post,... (found the right NON-Library version? even though its useless for me :P ) binary is still 1.xx by looking at change log it looks pretty much 2010...
Thanks for the encrypted AFAICU: looks like - As Far As I'm Concerned

Why don't you use some logics (and patience)? :dubbio:

LZOP
http://www.lzop.org/

Version 1.03
01 Nov 2010


LZO
http://www.oberhumer...lzo/lzonews.php

============================================================================
User visible changes for LZO -- a real-time data compression library
============================================================================

Changes in 2.06 (12 Aug 2011)
* Some minor optimizations for big-endian architectures.
* Fixed overly strict malloc() misalignment check in examples.

Changes in 2.05 (23 Apr 2011)
* Converted the configure system to non-recursive Automake.
* Applied some overdue speed optimizations for modern x86/x64 architectures
and current compilers like gcc 4.6 and MSVC 2010.

Changes in 2.04 (31 Oct 2010)
* Fixed a gcc-4.5 aliasing issue in lzo_init().
* Updated the configure system.
* Assorted cleanups.

Changes in 2.03 (30 Apr 2008)
* Updated the ELF assembler sources to mark the stack as non-executable.
* Fixed a HP-UX 11 build issue with Itanium in ILP32 mode.
* Updated the configure system.


There were NO "major" updates in LZO, or if you prefer, LZOP 1.03 is good enough.

Sometimes I don't get the "I want the latest", what has happened to your life/ccomputing power/computer knowledge/whatever since April 22, 2011?
LZO has been substantially UNchanged for 3 (three) years. (and most of the apps that actually use LZO still use 2.03 version).
It is a stable, mature project, used by a number of apps.

AFAICU: as far as I can understand

Basically I'm looking for something that decompresses (extracts) files at lightning speed :)


If you know of something better then this, care to share your findings?


edit: BTW the site itself is confusing with version numbers though i admit my impatience makes me jumpy (specially when i don't find "download" text etc)

what has happened to your life/ccomputing power/computer knowledge/whatever since April 22, 2011?

:dubbio: You really noticed that date... you're really something, one can learn a lot from you...

Yep, but the three main characteristics of a (lossless) compressor/decompressor are:
  • compression speed (and memory needed)
  • compression tightness (or compression ratio)
  • decompression speed (and memory needed)

HOW much of #1 and/or #2 are you going to "spend" in order to get #3? :unsure:

Go here and compare (more often updated than other sites):

seem like good horses to bet on. ;)

lZ4 is faster then LZO :) thanks! (hmmm, should've found this out on my own... :blush: )


Crush is CRUSHED (very bad) :ouch: and that site will be handy for wip check too.
