In need of crazy compression
mcm 0.83 : https://github.com/mathieuchartier/mcm/tree/v0.83
- Is there any research as to what's the best way to compress each file type?
- Don't Use RAR
- Is 7zip with lzma2 the best tradeoff between compression speed and decompression speed?

Help me out with some compression tips
A good trade-off is mcm : it uses SSE2 and MMX. It is not as good as zpaq, but it is better than LZMA2 (7zip) and really faster than zpaq. https://github.com/mathieuchartier/mcm

Don't Use RAR
I typically don't make use of standard archive formats these days for my own file storage. If I want just pure maximum compression, I'll often use a long-range matcher like FreeArc's srep [1] or lrzip [2] combined with either fast-lzma2 [3] using a p7zip fork [4] for multithreading or use mcm [5] or zpaq.
However, my truly preferred way is using dwarfs [6], which features some really good deduplication and (by default) zstd compression while being mountable. Most of my files are highly compressed and easily accessible without needing to full decompress them. Admittedly, I don't make use of PAR2 or anything of the sort, but I could just do that the traditional way if I so wished.
