Comsol 4.2 on big simulation machine

Hi to everybody,
I'm using Comsol 4.2 to run CFD and Conjugate Heat transfer complex models. First we used a machine called Machine1 (in the following text) which is a workstation. Than we bought a new machine (Machine2) to have more power and reduced analysis time. But this is not happened! The "expected to be faster" machine is actually slower.
Machine1 (Workstation):
Name: Dell T7500,
CPU: Intel Xeon E5620 2.4 Ghz, 2 processors (4 core each); RAM: 48 GB Ram Memory; OS: Windows 7 64 bit
Machine2 (Server):
Name: rack type Dell R715; CPU: Amd Opteron 6282 SE 2.6 GHz with 2 processors (16 cores each), RAM: 256 GB Ram Memory; Os: Windows Server 2008 R2 Datacenter Edition
Someone had experiences with this type of big machines. Me and my colleagues are mad about trying to configure the system.
We are thinking about some more optimized instruction to drive the calculations, to change the OS in a Linux Suse... and many others tests.
Any suggestion will be greatly appreciated!!!
Thanks!

We installed Linux SUSE on the server. Than we discovered that the main problem is the matricies assembly but not the effective used cpu time.
Coul be the problem referred to RAM usage?
