Actually the benchmark was done from my very normal and basic gentoo box, which had F@H client running at the time. It is a Pentium D, with a very very lightweight installation (sans kde lol), so guess that contributed.

I discovered that if you follow this ricers howto and bootstrap during a full moon my 3.2Ghz P4 o/ced to 5.8 liquid nitrogen cooled magically sprang up an extra 200Mhz clock making it 6Ghz!!.. Imagine what it would do if I did it during a solar eclipse!?!? the hidden CFLAG --fomfgwft-opts also works wonders.

I heard that if you patch "flame_decal.h" to the vanilla kernel, it makes it go faster. :D

Now lets see who else has seen that Futurama episode...

-omg-optimized

That had me in stitches.

But where are

-mtype-r
-mNOS

or maybe more appropriately for a computer

-mLN2

:D

Yea but it's exclusively distributed in the awesome_express patchset.

make sure you're using the 2.7 kernel series. whatever you do make sure the second number of the kernel is odd.

Code:
-msse3

damn must have missed that one... yeah I see it now right next to -omg-mmxadv and -m4dnow (used for rendering things in 4 "spatial dimensions") enabling...

As far i know the flag is available in gcc 3.4.x, but it only works really good on gcc >= gcc-4.2, so you really should upgrade ASAP.

Just a not-joking, serious note: I'm using an ~x86 system with a sempron 3100+ rev.E
machine.Since seems that I'm forced to use march=athlon-xp here (cause march=k8 is for ~AMD64 only),
I decided to add the cflags "-msse -msse2 -msse3", however, speed-up is very limited,
even for blender rendering(152 sec becomed 148) I think cause:
or 1) gcc isn't really good with sse2
or 2) sse2 needs optimized code to works
or 3) sse2 just doesn't give much performances (but strangely, sse2 versions of blender
for win32 is reported to gain more than 30% speed... which makes me think 1 or 2 are the correct answer...)
or 4) sse2 is just not supported for 32 bits enviroments (+athlon-xp)?

I can answer myself, right answer was 1 for gcc 3.4.x ,with a note:

even with -O3 -msse2 -msse3 -mfpmath=sse -mfpmath=sse,387 thing didn't changed too much, my renders becamed
only 6% faster than with a plain -O2.... (143 seconds)

answer was gcc 3.4 isn't handling well the sse-sse2 optimizations for fpmath(at least not as intel compiler does),
autovectorization is in gcc 4.1,so with gcc 4.1 it should perform more (but I can't thell how much).

EDIT: I did a test. The same scene in blender took me 2:32 to render in a blender built with gcc-3.5-r1 and just "-O2",
the same scene took me 1:55 to render in a blender built with gcc-4.1 and "-O3 -ftree-vectorize -msse -msse2 -ftree-vecorizer-verbose=1 -mfpmath=sse".
20% less time is good for 3D apps,as it can save hours in batch renderings, so IMHO with gcc-4.1.0 the 3D apps will be a little
exception to the gentoo ricing....

Well, you can't beat hand assembled SIMD code for the areas that are truely important. 6% isn't too bad.

And to all you ricers out there with slow machines, here is a nice ricer tip!:

Always emerge packages on faster machines because those binaries will also be faster when run on slower machines!

I've another sure-fire suggestion for further optimilazing your Gentoo-experience. Paint your computer case red, wear only red clothes and change your console colour setting to only output red text. As everyone worth his salt knows, «Red onez go fasta!»...

Umm... I better not post my emerge --info here :lol:

Sure the quite often forgotten prelinking makes wonders! Just remember to add USE="pic" flag and prelink all possible applications with all libraries they happen to use. Then find the preload/prefetch patches or Gentoo baselayout and you're golden.

Only that and the need for 4GB of RAM (or more...) because all that applications and libraries would be loaded upon boot into the memory in One Giant Swoop... But then, you'll be much rejoiced ;)

Just to be sure, I'm not missing out on some k3w1 basmati here: "pic" does stand for "prelinking insane combinations", right? :lol:

Code:

pic - Build Position Independent Code.  Do not utilize this flag unless you know what you're doing.

Someone fire up a 200 mHz CPU machine w/ 18 mB of RAM and maybe 2 gigs of HD space(I know people out there Gentoo these), and seriosuly try this out. Heck, who needs overcl0cking with this stuff!?

Brilliant piece!
