thought I'd post it here aswell as this really has a huge impact on wine performance.
just noticed that after using ./configure it set my flags to O2 and.. well, nothing else.
trying with theese flags now, to see how much better performance I can get 
export CFLAGS="-march=athlon-tbird -m3dnow -mmmx -fomit-frame-pointer -O3 -pipe -ffast-math -fthread-jumps -funroll-loops -falign-loops=2"
if anyone else has any suggestions to experimental flags that may pay off in performance (not like wine is that stable anyway  ) let me know |

| check the use pages on the frontpage. If you don't sett any optimalisations, you don't have much profit of compiling on your own machine |

| I know that, my main.conf has been configured and tweaked, but ./configure doesen't use em, becouse they arn't properly exported. |

Wow big time increase? This is almost the same question as in my other post here http://forums.gentoo.org/viewtopic.php?p=23391#23391
But any help would be great.
My buddy has a duron 900MHz and (I dont know much about duron and new to optimizing) running a geforce2 ultra with a via chipset, What flags would you guys suggest for that setup ???
Thanx in advance |

really don't know.. try looking on google for gcc 3.1 flags and optimization, you defenatly want the sse optimizations |

If you go look at the ebuild, you'll see that the wine maintainer specifically disabled optimizations. They don't play well with wine. |

this is the cvs version, the ebuild is old, and it plays VERY nice for me, BUT, ANY ./configure I run will NOT be with optimizations unless I manualy export CFLAGS first, that in the link to the thread regarding that subject. |

if I am not mistaken:
-march=athlon-tbird is implying -mmmx stuff? |
