Yes mate, you waste your time. You didn't put any arguments on table...nor counterarguments, instead you switch rails of topic (this patch or that patch, multicore or two, it was here or there etc.)
I know CPU isn't a bottleneck for LFS right now. I asked about something further, in which I am interested.
As TechEdison pointed 'you can play LFS on a potato', and it's great considering how flexible and accurate this code is! So instead of empty blablaing run your imagination cargame, and try to see what can be achieved in LFS with mid range hardware we have now. See?
