Well, heres some compile tests using the towers of hanoi benchmark. It compares using the i386 march to i686 aswell as comparing -Os to -O2 and other optomizations. I use -pipe -fomit-frame-pointer -march=i386 -mcpu=i386 for my C/CXXFLAGS.
Benchmark: http://www.dcaf-security.org/compile-test-1.txt

| Use -static. We hate libraries. Hds are big and redundant code isn't a problem, but loading times suck, so get rid of libraries and stuff everything into the executable. |

Leave that one out. That's not what the static flag does. |

There's a difference between daft ricer misinformation and just being plain incorrect... |

Hmm is it really that wrong? I thought as long as you have static laibraries (.a) and link an executable with -static all code from static libs get into the executable - which is basically what I proclaimed. I know that not all libs are built static, but well.

add "static" to your USE flags and ad "-static" to your LDFLAGS

One of the most useful tools has been completely forgotten:
app-benchmarks/acovea. Acovea never lies! Best used without thinking twice what this actually does and how it works. I did emerge -e world with the flags it gave me and my system feels at least 1,4% faster now.

That is definitely a good one. You should run it with lots of stuff going on so you get your system optimized for a dirty environment and I would run it only once since it is so reliable. |

In defense of acovea, I've found that the best thing acovea did for my system was give me a set of very stable CFLAGS. I used to use -O2 and/or -Os, but there always would be some package that would break while compiling.
Here's my CFLAGS, generated by acovea:
| Code: | | CFLAGS="-march=pentium3 -O2 -mno-align-stringops -minline-all-stringops -fno-crossjumping -fmove-all-movables -mno-push-args -fno-delayed-branch -fno-thread-jumps -fno-defer-pop -Wall -pipe" |
Which seems like at first glance that I'm uber-ricing my machine, but on closer inspection will show that I've actually got my CFLAGS somewhere between -O1 and -O2. -O1.5, if you will.
I would highly recommend that if you decide to run acovea, that you do so when you're on vacation.

I have used acovea. I just feel the results it gave me were not very good. So I decided to go back to very conservative CFLAGS. |

All uber ricers have to expand their CFLAGS especially when filing a bug report.
| Code: | | -march=pentium3 -O2 -pipe |
-O2 should become:
| Code: | | -fdefer-pop -fdelayed-branch -fguess-branch-probability -fcprop-registers -floop-optimize -fif-conversion -fif-conversion2 -ftree-ccp -ftree-dce -ftree-dom -ftree-dse -ftree-ter -ftree-live_range_split -ftree-sra -ftree-copyrename -ftree-fre -ftree-ch -fmerge-constants -fthread-jumps -fcrossjumping -foptimize-sibling-calls -fcse-follow-jumps -fcse-skip-blocks -fgcse -fgcse-lm -fexpensive-optimizations -fstrength-reduce -frerun-cse-after-loop -frerun-loop-opt -fcaller-saves -fforce-mem -fpeephole2 -fschedule-insns -fschedule-insns2 -fsched-interblock -fsched-spec -fregmove -fstrict-aliasing -fdelete-null-pointer-checks -freorder-blocks -freorder-functions -funit-at-a-time -falign-functions -falign-jumps -falign-loops -falign-labels -ftree-pre |

I would prefer to have my real make.conf and then a make.conf to use to file a bug report. It can't be the CFLAGS so why give them the correct CFLAGS information in the first place. |

Thanks for getting on-topic again.
You are correct, but filing bug reports with empty CFLAGS will make those devs suspicious. Worse, they might even ask you to set the dreaded -g flag and not use the strip option...
BTW, doing this:
find /etc/ -type f -exec sed -i '/^#.*/d' \;
will make every app that reads configs from there go faster because they have to read less comments, which they discard anyway!
Remember you will have to run this after every etc-update again, so you might want to make this a cron job too!
(( Note: it will also break your init scripts and others, but hey, rebooting is for wimps anyway! ))

Oh my god, this topic rocks!! I'll try the uber ricer opts on a few apps 
but I guess some won't work on my amd64 ^^
really good job there! |

I like it. And when I get some time (swamped with wine/WoW/actual work stuff now) I'll put it in along with some other entertaining bits.

While you are at it, add something to strip the comments from all the shell, python and perl scripts from the system. That should make them all go extra fast since the interpreter won't have to waste time reading comments. |

in the spirit of funroll-loops?? it seems to me that the funroll guys put that page up humourously but also with some malice towards gentoo... yeah its funny, but i think they really meant some parts of it to insult gentoo and the community. so, with that, id say its not in the spirit of funroll...
* i havent visited their site since it first went up, and i dont remember them ever saying the whole is a big joke, nor have i spoke to them so i might be wrong and it is just a big funny joke. my bad. |

By "in the spirit of funroll-loops", I meant the humorous aspect. I don't really care if they're mocking us as a community or not, the fact remains that they are correct about ricing. The purpose of this is to (hopefully) turn people away from ricing, just as funroll-loops should do.

dammit people, personally I just laugh at the people who laugh at gentoo, i can sit back safe in the knowlege that they are pathetic trying to argue about what distro I use!!!!!!! I've used russian distros before so im not worried.
I love gentoo because, lets face it, im lazy and i cant be bothered with the problems i got with mandrake, and to a lesser extent fedora and debian.

If you don't want to break your init scripts, use sed address ranges. 2,$ should 'work'. |
