I *don't* want to start some flamewar her, I am a newbie in this group, and I just would like some info on how to do it right, as my extensive rtfm'ing/googling/etc. has still not given me a satisfying answer.
I started my Gentoo-installation with CFLAGS containing -O3, believing to do it right ... Now I read about the fact that -O3 results in bigger binaries and isn't at all guaranteed to give me a faster system. The bigger files result in more load on IO, so this tells me that it puts the load on the (relatively slow) 5400 rpm HDD I have in my laptop. OTOH I have "only" 512 MB RAM in there so it seems interesting to me to go the -O2 way of doing Gentoo ... Now the question: Do I have to do "emerge -e --newuse world" on my system or what else would be needed? Is it worth the effort or should I prefer to spend the cpu-cycles on re-emerging only the core-apps of my system? Or forget about it all and enjoy my nice and shiny system as it is, simply editing make.conf to use -O2 for any new emerges coming? I am not asking this to get the "best result" in terms of speed or performance, but to make sure that I don't break my system (which has been backed up, sure, thanks ...). Greets and thanks, Stefan. -- gentoo-user@gentoo.org mailing list
