The result seems to be obvious ...

The first method extracts correctly in 9 min... the second method I not tested the extraction...

The first method is the correct way to get a small size.
The second method is not good. You noob guy's precompressors goes first always. |

Lol all this comments and tests to know the smallest Guys it's extremely plain , ofc srep64+zcm after the pre-compressor will be better
it would be a waste of time & data & ratio if u used it like this srep64+pzlib+zcm it's look like u're telling arc to compress then decompress then compress so why the first one !!

Not always, sometimes you just have to be smart, a precompressor can come after srep, that is if you're compressing some data that has a lot of repetitions of the same thing provided it has zlib streams, especially if they are big.
I can provide you some file that is compressed using level 9 and memory 1 zlib method, and it is compressed to 10mb, I then make repetitions of the 10mb to a 1GB file, there's going to be 100 repeated streams because 10x100 = 1GB. If you apply a precompressor first here, remember I said memory 1, this is the slowest setting so the precompressor will process the same stream at very slow speeds 100 times rather than telling srep via command that there is a repetition, it should only accept a minimum of 10mb repetitions, srep will combine all those repetitions then precompressor will only process that one stream, meaning you will get same ratio while getting 100 times more speed, who's the noob now? But in order for you to notice this, you have to thoroughly check the input you're about compress before compressing before making this attempt of making a repetition reducer before a precompressor.

srep+pzlib+srep+lzma, a very weird method but it should give roughly ratio, obvious that ratio will be a bit bigger but you gain speed. Last edited by Razor12911; 18-11-2016 at 21:19. |

A pre-compressor, as rule should be put at the beginning of a method, which alters the content of the file, so that a compressor will get better results, that without pre-compressor ...
Logically everyone can experience any concatenated method, for better compression ratios or best speed of execution, but unaware of a new discovery in a new concatenated method, you can encounter errors during decompression. Compression : "pzlib+srep64+lzma" In= 1 GB / pzlib = 2.07GB > srep64 = 2.23GB > lzma = 466MB /T = 00:04:50:48 "srep64+pzlib+lzma" In= 1 GB / srep64 = 1.0GB > pzlib = 1.54GB > lzma = 697MB /T = 00:04:48:45 "srep64+pzlib+srep64+lzma" In= 1 GB / srep64 = 1.0GB > pzlib = 1.54GB > srep64 = 1.65GB > lzma = 685MB /T = 00:05:05:40 "pzlib+srep64+pzlib+lzma" In= 1 GB / pzlib = 2.07GB > srep64 = 2.23GB > pzlib = 0GB > lzma = 466MB /T = 00:05:10:30 ************************************************** ************************** Decompression : pzlib+srep64+lzma = OK - /T = 00:01:18:965 srep64+pzlib+lzma = ERROR srep64+pzlib+srep64+lzma = ERROR pzlib+srep64+pzlib+lzma = OK - /T = 00:01:20:59

My tv is smart. You got speed because the first step of the method srep, resuce the size of temp file

@chronocross (did you know flac compressor is better than tak and tta for compress wav audio files. Now you learn something. ) i'm not talking about pzlib place in methods
