RT!

Computer is the savior R7000 4800h 32GB memory, system Ubuntu 20 (vmware 5.xx)

The target kernel for compilation is version 5.6.18

Generally, make -jN is used for compilation; is it better to set N to the total number of CPU cores or the total number of threads?

16, AMD's multithreading optimization is not that bad, if even the compilation chain can't be optimized to adapt to hyperthreading, then there is no point for other applications

threads * 1.5-2 best

I saw on Xigua Video that "Architect Adam" used Lenovo Savior 4800h to compile 5.4.x and used make -j8 instead of -j16
