[Beowulf] 10 GbE vs. Trunked 1 GbE performance?

[Steve Cousins]

We are purchasing a NAS NFS server for our cluster and I'm wondering if a 
10 GbE card would give us twice the performance than say 4 trunked 1 GbE 
lines.  Given that the NAS itself has the performance to drive this, do 
any of you have real-world numbers comparing this sort of thing?

Thanks,

Steve
