Just FYI... While compiling kernels for BeagleBone Black and Raspberry Pi Zero 2W, I encountered the following speed ranking:     - Kubuntu -- bronze medal  (~130min)     - Mint -- silver medal (~120min)     - LMDE -- gold medal (~110min) I don't know why there is difference between Kubuntu and Mint.  Both are on LTS base, and kernel compile doesn't go through desktop.
