Вопрос ISDone 0.6 final, decompression speed

[nizcoz]

I am using ISDone 0.6 final with arc compression. When I run the installer, decompression causes the installer to run slowly. What is the best method of decompression but at the same time the decompression is fast?

nizcoz, use Facompress_MT

 

[nizcoz]

How to use facompress_mt? How to compress with it?


Arc.ini

[Default options]

[Compression methods]

[External compressor:srep]
packcmd = srep {options} $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep -d - - <stdin> <stdout>

I have the same results with a normal compression with FreeArc (Normal: -m4 -s128m) or with -m9x -ld192m -s256m (asymmetrical) or maximum (-mx -ld800m)


I am using FreeArc program to compress my files, i am not using the command line to this (arc.exe).

So, what is the best method of compress/decompress but at the same time the decompression is fast? (with low cpu usage).

How to use facompress_mt? How to compress with it?

it is only for decompression, surch it here how to use

@Pipocooling It is difficult for me to find the explanation on this. Here I found something but I do not understand how to use facompress and facompress_mt:

How to use facompress?

 

[Pipocooling]

nizcoz, add this to your script, and add Include this files in your installer

#ifdef facompress
Source: {#IncludeFiles}\facompress.dll; DestDir: {tmp}; Flags: dontcopy;
Source: {#IncludeFiles}\facompress_mt.dll; DestDir: {tmp}; Flags: dontcopy;
#endif

 

[nizcoz]

And then extract this files in my code?

I am using to compress my files FreeArc for windows (high compression). Facompress works ok with this? I must use both files (facompress.dll and facompress_mt.dll) at the same time?

And how to use fazip?

Thanks.

 

[nizcoz]

Is it ok?

#define facompress

[Files]
#ifdef facompress
Source: Include\facompress.dll; DestDir: {tmp}; Flags: dontcopy
Source: Include\facompress_mt.dll; DestDir: {tmp}; Flags: dontcopy
#endif

[Code]
#ifdef facompress
    ExtractTemporaryFile('facompress.dll'); //.arc Accelerates unpacking archives.
    ExtractTemporaryFile('facompress_mt.dll');
#endif

 

[Булат Зиганшин]

both dlls are used automatically by freearc programs. facompress_mt speeds up xppmd method which is hardly useful for game compression. facompress is really useful but may improve speed only by 10-20% - the difference is only that it compiled with more efficient compiler than main freearc executables

 

[nizcoz]

Then, do you recommend using only facompress.dll to decompress .arc files?
