Performance about sevenz-rust HOT 4 OPEN

This library does not currently support multi-threaded codecs, it may in the future

from sevenz-rust.

Due to my app specifications I had to swap to the 7z CLI app to make the decompression run faster, loosing the progress bar in the process. I did try to make changes to the library to make it multi-threaded but my current knowledge of Rust just isn't enough at this point :c

Well, I think the best way is to support lzma2 multi-threaded codec, just like the fast-lzma2 library, but it is very difficult to implement.
But there is a simple way that works for non-solid compressed 7z files. You can check examples/mt_decompress.rs in the mt_decompress branch
