I want colors, but not light cyan and light green. But
I don't rely on htop enough to change this. I believe
the red and yellow theme of top (the one in the
screenshot) is configured though.

If you are into the "top business" there is a large
article on this in Linux Magazine, a max 3-4 issues
back.

All this depends. I'm not sure Emacs-spawned processes
will run slower on the dedicated Emacs core.
Compilation in practise is compiling small changes all
the time, not huge recompilations. Even so, it isn't a
good example as this was never about doing batch jobs,
it is about increasing the interactive feel and touch
responsiveness of Emacs. And this actually happens.
