This doesn't make sense, how can you add level for decompression? Brute is not reflate or made based on raw2hif, level setting is something that reflate does itself, brute on the other hand is search every byte then decompress.imagine a 794mb file, it has 832 618 624 bytes, brute must use trial and error for every single of those bytes starting from 1 to file size, brute checks about 200000 bytes per second on my cpu, I dont think that is slow.

Mine was only a hypothesis and a request on a product that I do not know, I can not know with what structure and concept compresses a file, we are talking about "Fast Brute" and therefore hypothesized the possibility to make it even more faster.:)
I like to be informed about things, especially on issues that interest me, sorry for the chatter.:p
P.S:Do not use the noun dude, it's unpleasant.;)

Is impossible not compare brute with precomp or reflate. But each of this tools are very diferent and unic. The concept to brute in applications always is very power and slow. I was spend 17hs to test folder in brute mode on my own compiled version of precomp. But in fastbrute only spend 1.30hs and the results are very close. The test was made it without any pipe chain with compressors.

Good job bro, i want to congrat you for keep helping community for long time.

My test with GTAV x64w.rpf 893MB.

Bilawal reflate+srep+lzma -> 498MB in 451 seconds.
FastBrute+rep+delta+exe+lzma -> 558MB in 1426 seconds.
fastbrute+srep+lzma => 526MB in 758 seconds.


Precomp with brute mode is too slow for GTA 5 file.

As I know razor now adding fast brute to pzlib, so pzlib will have all the fast brute features!

felice2011 06-06-2016 23:42

I put myself in the queue I too waiting of mature updates, especially for PZlib.:)
