I have some Unix systems that performed very well when backing up to a 1Gbit 
connected DSSU Media Server.  However when that Media Server NIC was upgraded 
to 10Gbit the performance dropped dramatically (85 MB/sec > 40 KB/sec).  When I 
point these Unix systems back to another 1Gb Media Server then they are fast 
again.

Windows clients do not seem to have issues.

Is there any tuning / tweaking that needs to be done for Unix systems to 
perform well to backup to a 10Gbit (Windows) Media Server ?
