I *don't* want to start some flamewar her, I am a newbie in this group, |
2 |
and I just would like some info on how to do it right, as my extensive |
3 |
rtfm'ing/googling/etc. has still not given me a satisfying answer. |
4 |
|
5 |
I started my Gentoo-installation with CFLAGS containing -O3, believing |
6 |
to do it right ... |
7 |
|
8 |
Now I read about the fact that -O3 results in bigger binaries and isn't |
9 |
at all guaranteed to give me a faster system. The bigger files result in |
10 |
more load on IO, so this tells me that it puts the load on the |
11 |
(relatively slow) 5400 rpm HDD I have in my laptop. OTOH I have "only" |
12 |
512 MB RAM in there so it seems interesting to me to go the -O2 way of |
13 |
doing Gentoo ... |
14 |
|
15 |
Now the question: |
16 |
|
17 |
Do I have to do "emerge -e --newuse world" on my system or what else |
18 |
would be needed? |
19 |
|
20 |
Is it worth the effort or should I prefer to spend the cpu-cycles on |
21 |
re-emerging only the core-apps of my system? Or forget about it all and |
22 |
enjoy my nice and shiny system as it is, simply editing make.conf to use |
23 |
-O2 for any new emerges coming? |
24 |
|
25 |
I am not asking this to get the "best result" in terms of speed or |
26 |
performance, but to make sure that I don't break my system (which has |
27 |
been backed up, sure, thanks ...). |
28 |

Greets and thanks, Stefan. |
