Mrxlazuardin is on a distinguished road

I don't understand why Fluent running with 32 processes on dual nodes is slower than Fluent running with 16 processes on single node? Each node has four Quad Core Opteron CPUs with eight 2GB RAMs and GbE NIC. I'm using Windows Server 2008 x64. I need suggestion how to optimize this dual nodes configuration.

Best regards,
