Hello! I want to know why you use tarlz. If I right understand, you use tarlz archive format (not usual tar.lz or something else) because it has multi-threaded facilities. Am I right?
I read the source code of qi and found that qi uses tarlz with option --solid. It means that tarlz can't unpack this archive with using multi-threading [1] [2]. I understand that you want to get the smallest possible size of an archive. If I have a fully empty disk with 1TB capacity, I may want to get more speed especially if I build packages for testing (not for release)... I want to propose you to add to qi possibility to point compression granularity level through new option or maybe through qirc file. Note: I don't propose to change default compression granularity level. I simply want to have a possibility to change it when I want it.
