How many treads were used by wine and how many were used by windows? Just a small example: using 4 and 6 threads in wine. It's a small improvement, but I only have 4 cores and threads. Your cpu might use 4 cores and 8 threads, if you haven't done that already. These tests where done using the command line version 9.13. The wine version is current git.

The wine version seems to be faster than the native 32bit version. There might also be differences in the compiled 7zip executables (different optimization options?).

These show the cpu usage (%), R/U (MIPS), Rating (MIPS). On the left side compressing, on the right side decompressing.

How fast is your native linux executable? Could you try different thread counts and compare them?
