I will add all those numbers to the performance webpage mentioned earlier.

The main optimization in Hash Suite is not in the "format" itself but
in the key-generation and found matches process. This ideas can not
apply easily in john without break support to many other options. But
there some "things" that i was planing to add when i have some free
time/supported hardware:
1- Eliminate in 32 bits version the use of 32 bits register. This
improve performance in old CPU (when i wrote initially the asm) but
currently i think it slow down performance.
2- Eliminate the full binary and only use partial (for table hash lookup).
3- AVX support. I think we need for this AVX2 with integer support.
