Figure 11 - 10GbE Large Sequential Read Performance
A single NFS client with a 10 Gigabit Ethernet connection to the NFS server was tested as well. In
this case the NFS client had only a 10 Gigabit Ethernet card (and no InfiniBand card). Both the NFS
client and the NSS server were directly connected to the PowerConnect 8024 10 Gigabit Ethernet
