Let's talk zipping files, specifically 7-Zip

I zip large folders (from 12 to 30 GB) using 7-Zip (to be referred to as 7z).  It seems to take forever but does finish.

As I'm typing this 7z is zipping at a 73% compression ratio at 18 MB/s.

That said, I was also watching a vid of a review of some laptops, the review using 7z to compress and decompress folders of some size, they didn't specify, using the build-in 7z benchmark tool.  On the screen was the results from a lot of different cpu testing.

Their numbers indicated speeds of around 36 MB/s compression and around 477 MB/s for decompression for my Ryzen 5 3600.

I know I'm leaving out a lot of specifics but are there some things to look out for when setting up 7z to get me some more speed?  36 MB/s means twice as fast and, as they say, time is money.
