docs (lzip): add lzip to benchmark and replace "LZ4, LZ45" in README.md by "lzip (LZ4, LZ5)"

[GitMensch]

Quoting from https://sourceforge.net/p/sevenzip/discussion/45797/thread/32771d84/#e23d :

Hello,

I added the lzip patch to my modified 7-Zip version, which also has LZ4, LZ5 and Zstandard multithreaded compression / decompression in it...

And its in the docs, too. Shouldn't it be added to the README.md (and maybe the tags)?

[mcmilk]

The README.md has a note about it:

included lzip decompression support, patch from http://download.savannah.gnu.org/releases/lzip/7zip/

Just search for lzip here: https://github.com/mcmilk/7-Zip-zstd

[GitMensch]

Hm, ok, I see the note now. I think I was blinded by the headline teaser and the codec list naming LZ4 and LZ5 and the nice benchmarks only about zsdt and LZMA.

[mcmilk]

Yes, measuring the decompression speed with LZ4 or LZ5 isn't usefull with the 210MB Silesia compression corpus... I am searching for some inofficial bigger corpus.... so they are not included in the benchmark... currently.

If someone can help me with that, just do it ;-)

[GitMensch]

Can I suggest to change all occurrences of "LZ4, LZ45" to "lzip (LZ4, LZ5)? Or did I get something wrong here?

Why not?

[mcmilk]

It's simply to fast. The measuring time will be small to get valid results :-)

But I will create some own compression corpus for this and put it onto github...

[mcmilk]

Lzip is not supported by the "plugin only installation" ... only the full setup has support for it. So there it is in the documentation ... everything is okay with it.

[GitMensch]

Side question: What are the reasons for Lzip not being available with the plugin only installation?

[mcmilk]

It's not possible... that's the reason. I included the lzip patch from http://download.savannah.gnu.org/releases/lzip/7zip/ to the own full setup... nothing more.

The patch does not create plugins... ;)
