Maya 7 For Linux, Renders Slower Than Windows

[melt]

Hi there,
I just installed Maya 7.01 to Suse64. My configuration is, Amd x2 Dualcore 3800+ with 2 gigs of ram.
Here is the problem, i get the test scene ( from zoorender.com ) , and rendered it with linux. Rendered in 1:15. The same scene with Windows, 1:05.
It's not possible windows to render faster than linux..i used to use maya on linux before...now i changed my configuration and it renders slower than windows...
i've got smp kernel installed and it seems maya uses both of the cpus while rendering..Can the problem be about Suse ?? Do i need to install 32bit version..or another distribution maybe ?
Thanx a lot

The render time issue may be related to several factors such as a graphics driver, though I believe it's due to using a 32-bit application (Maya 7.0.1) running in 32-bit compatibility mode with a 64-bit processor (AMD Athlon 64 X2). Alias compiled and optimized Maya to run on 32-bit processors not 64-bit with the exception of Mental Ray Standalone 3.4.5. I do hope with Autodesk acquiring Alias that they seriously consider compiling Maya for 64-bit Intel and AMD processors. While it's nice to still be able to run legacy applications on 64-bit processors it would also be nice to see Autodesk help Maya catch up to competitors such as Softimage (XSI) by offering a binary for 64-bit. After all, future Intel and AMD processors will all be 64-bit capable and like I said competitors such as Softimage offer highend studio software compiled for 64-bit now. Anyway like I also said Mental Ray Standalone 3.4.5 (see http://usa.autodesk.com/adsk/servlet/index...3112&id=6837573 ) is offered for 64-bit which is supported on SUSE Linux and RHEL.

Yes, the same with me here, too. I installed maya on an 32-bit redhat system and on one 64-bit system, and there was still a 10 second difference on both (56s win, 1:06 linux). The compatibility mode would also be the case on win xp 32 bit or?
it would really be interesting what is causing this _huge_ difference.

Alias already has it in the works. They showed off a beta of maya 64 bit at siggraph last year.

Total guess here, but it might be ready for siggraph 06? donno, but I hope so.

because it is a 64 bit OS running a 32 bit program though a compatibility layer. Your going to loose speed with any type of compatibility/emulation layer.
