Fazip is an external compression library used by FA with internal compressor "rep, mm, delta, exe, exe2, 4x4, lzma ... etc", in some cases it can also be used for reading (stdin-stdout) of some external compressors (ex.LOLZ).
The example shown concerns external compressors, with a single configuration with FreeArc support.

So you will have differences in compression ratio and speed using the following methods:

Code:
srep64:m5f:a2:d1g+lzma2:d512m (LZMA2)
srep64:m5f:a2:d1g+lz77 (LZMA)
srep64:m5f:a2:d1g+lzma (fazip)
logically everything changes according to the configuration of the.ini file

i'm asking questions and they don't see it,
they fight for billionaire ;):p:D
hahaha very funny...

i'm not programmer so when you guys tell me something please be simple
cause i don't understand. :p

I Do more testing and i finally got this, i will use this for 6GB RAM Games.
and the 4GB Ram games i use 512 or 1024 depends of precomp.
so please guys tell me how to change and what is the MC ?
lc8 should be stayed as 8.
i like to change the MC but don't know what it is so please Explain :o

Code:
lzma:a1:mfbt4:2048m:fb273:mc1000000000:lc8
This 2048m req 21000MB (21GB) RAM for Compress
and Decompress only use 2050MB (2.05GB) with precomp and srep
it use 3100MB Ram.

i'm gonna do something better so that's why i need to know what i can still do for LZMA to get better ratio
when i done i will post it on here :p so help me guys.

what is your recommend ?

and pls tell me what is that MC ? :)

MC:
Quote:
Sets number of cycles (passes) for match finder. It can be in range from 0 to 1000000000. Default value is (16 + number_of_fast_bytes / 2) for BT* match finders and (8 + number_of_fast_bytes / 4) for HC4 match finder. If you specify mc=0, LZMA will use default value. Usually, a big number gives a little bit better compression ratio and slower compression process. For example, mf=HC4 and mc=10000 can provide almost the same compression ratio as mf=BT4.
@yasitha .... @KaktoR has already given you some references to read on some web pages, do not waste any more time with all your tests on lzma/lzma2/fazip, listen to our tips and our examples and start to compress.

In Italian and in our country, in Naples we say: "Sta' senza pensier !!!" :D:D;)

lolz on I7 8700K USE
[External compressor:lolz]
header = 0
packcmd = lolz.exe -dtb1 -fba4096 -mc1023 -pc4 -mt12 -mtt1 -d96 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

you should get around 4mb/s to 5mb/s

as for lzma just use lzma:a1:mfbt4:d512m:fb273:mc10000:lc8 no point of using d larger than 512mb it only improve like 10mb to 50mb...
Thanks :) Finally ;)

yes i see that i though it was only for 7z not For FAZip, sorry my bad :o

yasitha 26-12-2018 11:25
FAZip64 only use 25% 35% CPU Usage, how can i change that to 75% CPU usage ?
if i do, the process will be finish fast. :)
Help!

i know him personally we are friends is long time i think 5 or 6 years, now he's too buys can't even talk..
hes the best person that i know.
he can do anything pretty much. :)

and i miss him :o , wehn i need something i directly ask him,
so i don't have to wait,

i have provide him conversion graphics for ASC i think its in 2013 :)
back then i don't do compress, i don't even like it :D

recently i thought learning about it is a good idea,
casue new games are like huge :D so that's why i ask around! ;)

lzma limited to 2 thread faster use 4x4 but you need to lower d2048 to somthing like d32 or d64
you wont super fast lzma use 7z.exe
or as i mentioned in https://www.fileforums.com/showpost....8&postcount=25
use 4x4:lzma:a1:mfbt4:d32m:fb273:mc10000:lc8...
don;t get angry on me :D testing now... :)
angry off :D

yasitha 26-12-2018 11:40
this will keep the CPU Usage At 100% All the times
and that's the one reason i don't like LOL ZZZZ
second reason its slow.. and im testing now this lolz method,
and i will compare with my Current LZMA settings.

[CODE]
lolz:dtb1:fba4096:mc1023:pc4:mt12:mtt1:d96[\CODE]

you also can add 7z.exe and 7z.dll
and add to arc.ini
[External compressor:lzma]
header = 0
packcmd = 7z.exe a -txz -an -mcrc=0 -m1=lzma2:d384m:fb=273:mf=bt4:mc=999999999:lc=4:lp= 0 -mmt=12 -mx9 -si -so <stdin> <stdout>
it will use all 12 threads with 27gb of ram and decompresion around d384m
can't even type while lolz runing :D

i know 7z is fast lzma2, but lzma better then lzma2 i'v seen it with testing..
i do many many testing now im going crazy... :D
that's why i ask random questions..

did you learn about this stuffs on your own ? ;)
