Bulat, let me thank you for great tools you've created. Without them most repacks would be impossible, I guess
Now to topics you've mentioned.
1) Yes, now I'm aware of it. Could you please clarify if decompression threads number can be controlled by setting more dmem? Let's say I compress with 4x4:lzma256, what should I do, so users with 8-cores and GBs of RAM could decompress it in all their threads. I specifically put higher dictionary sizes here, cause smaller ones aren't good for compression ratio.
2) Yes, I've been talking about mode without blocks splitting and for sure I use it only on data with lots of already compressed data.
4) That would be cool, if it make decompression faster
Thank you again!
