It is certainly possible that this could be I/O on the RAID 5 causing issues, 
but occasionally we have several folks moving many gigabytes of data 
simultaneously over gigabit ethernet.. The connection seems to just get 
saturated.  I could probably test the I/O during a large network copy in the 
future, but this seemed a logical step since I had the extra interface 
sitting idle.  

As a side benefit, I got to learn much more about linux routing.
