Code:

"BCM is a high-performance file compressor that utilizes advanced context modeling techniques to achieve a very high compression ratio. All in all, it's like a big brother of the BZIP2."

How does BCM shape up against lolz/rz? Do you have any comparisons?

shazzla 05-07-2020 06:23

Both of them are better in many case.

Very good,thanks!
But i have to ask and sorry for my noob question:
What is the correlation between chunk size and block size?
It is not clear for me...

Block size settings is for BCM, it's BCM block size settings and for chunk we set how much data should be send through by BCM ..
You can always set block size to 9 for better compression, because still we using chunk size is about 64mb

@shazzla, block size corresponds to this

shazzla 07-07-2020 04:17

Ohh. Right. It was a dumb question. Sorry.

Dumb questions get dumb answers, you got 2 good answers so your question must have been a good question. ;)

Hi friend,
BCMX works perfectly to compare other compression tools. But it was gave a bad results in PAK files. Why it was happen? But it was worked perfectly another type files. For an example: I was compressed x.pak(21 Gb), Output was 9.77 Gb and also i was tried with xz or razor or lolz given nearly 8.9 Gb.

try again after changing the parameters (-b). and also change the chunk size (64m, 128m, ...).
