What flags can I put into my /etc/make.conf file before install my system to improve the performance?!
I have a K6-II 450Mhz 156 RAM ..
Thanks ...

Scroll down to the bottom and it well tell you waht flags to uncomment. (I am assuming this is before you have installed Gentoo's base system..)

l guess you are looking for flags like these:
| Code: |
CHOST="i586-pc-linux-gnu"
CFLAGS="-mcpu=k6 -march=k6 -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-mcpu=k6 -march=k6 -O3 -pipe -fomit-frame-pointer"

don't know if gcc3 will speed up your cpu, but it surely will several applications. but unless you are already rather familiar with compiler issues, don't try to switch to gcc3, it's still a little .. nifty

I too have a K6-2 450mhz and also a PII-233 mhz 
Those are my main reasons for wanting to try Gentoo - a blazingly fast linux system (I hope).
I read in the GCC 3.1 release that it contained optimizations for mmx, sse and so on.
K6-2 has mmx support, right? I didn't see any mmx flags in your flags.. are they automatically included when you select mcpu=K6 ? doesn't K6-2 have improvements over plain K6 ?
p.s. I too, am looking forward to the release of Gentoo with a GCC-3.1 (incl. glibc compile patch) - or perhaps we'll have to wait until gcc plans to deliver gcc-3.1.1 (june/july).
