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

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

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, ...).
