i've a dual xeon 3,2 64 bit machine, wich is the best way to use all my cpu power to render with blender?
i mean can i use both the processors?
i'm planning to have dual boot, win e linux so don' t worry about os.

Say I have an animation that is 200 frames in length.
I'd do the following from the command prompt:
blender -b myfile.blend -s 1 -e 100 -a &
blender -b myfile.blend -s 101 -e 200 -a &
Then you can use blender or another program to link the two outputs
after they are rendered.
That should be all you need to do.

So if the hyperthreading is enabled/disabled through bios, what does the "use threads" switch in blender do?
I tested the HT option on a 50 second render and found it decreased to 47 seconds, a 6% decrease in render time.
The test Bullx did (with 28% decrease in render time) is not an accurate benchmark since he crippled the OS. Basically, the render performance increase is overshadowed by increased system performance. It's like comparing systems with different CPU's.

Yes, you are right. Also, if you want to speed things up, download an optimized build for your system. I offer builds for Windows which can speed up rendering by more than 40%, however, I haven't updated them recently. If you don't use Windows, I think there are optimized builds for Linux and OSX as well.
Just check graphicall.org.

WOW, dowloaded the alpha 1 SSE optimized version you did mchs3d, got a 20 percent decrease in render time
That's in comparison to alpha2 version
Many thx for the tip.
Umm, I assume I copy the exe to the blender folder to use it, correct? Cuz that's what I did and everything seemed ok.
I compared the SSE build to RC1, they were about the same render time
