Hi Dave,
 
Could you tell us a little more about the usage of the networker server?
Is it used to only receive metadata and do scheduling or do you have tape 
drives/disk drives attached. What is the throughput of data through the NIC on 
the backup server?
What speed is the ethernet adapter set to. Is it locked to full duplex or auto 
negotiate? This may not affect you, but with older 100Mb networks this was a 
factor.
Similar question for the switch port it is connected to. What speed setting is 
defined?
Have you tried the bigasm directive to push a large file through this 
connection proving it is directly related to the speed of this new 10Gb link?
I assume you have applied the TCP keep alive settings to maintain your long 
running sessions. By your description though that would not be your specific 
problem
Regards 
Andy
