p { margin-bottom: 0.21cm; } blender works better in windows 7

hi, i’m a new user of blender. I’ve installed the software in a machine with two operating systems working on it: ubuntu 10.10 and windows 7 professional. I’ve downloaded a model from here:

nextwavemultimedia.com/html/3dblendermodel

the sofa set is the one I chose.

first I’ve made a test of rendering time of that model in the last released beta version of blender. In ubuntu it took a rendering time of 27 minutes, five seconds. In windows it took 14 minutes with 45 seconds.

I thought that possibly was the version of blender and then I installed the version 2.49b in both systems again. This time was bigger the difference, in ubuntu toke about 31 minutes, in windows 16 minutes to get finished the render.

it isn’t supposed to be faster blender in linux? I didn’t change anything in preferences and configuration of the software. Someone can tell me why this happened and how to get a better performance of blender in linux? I’ve recently started to use ubuntu and I love it, but I need a good performance specially in this software, and it would be sad to use it on windows.

my computer is a notebook hp pavilion-dv5, with amd athlon x2 processor and an Ati radeon in graphic card.

thanks in advance.

I noticed this too, but on Vista 64 vs ubuntu on my laptop. Vista was marginally faster there. But dang, nearly DOUBLING the speed? That says to me that something is just not right. You sure it’s making full use of the cpu? ie all cores are being used?

I could not believe, :eyebrowlift: my system renders “Sofa Set” in 2.20 minutes but i don´t have a dual boot system to test on windows. I read about 15% difference linux/windows, are both systems 32/64 bit systems?
Very strange.

Maybe some other program? there will be huge difference in performance if for example you have heavy flash in one of firefox tabs in background.

And in ubuntu there are some awful IO bugs which affects performance. Because of this I use optimized gentoo as my OS for rendering and drawing (and other heavy computing tasks).

No Windows version ever can beat custom build Linux kernel specially for rendering and with ultra light weight GUI for desktop. And of course no background processes!
