Vista - Enabling Jumbo frames on NICs

My network speed was below 22 MB/s with 1500 byte frames.

I set my X7DWA-N Intel NIC to 9000 byte frames. My Thunder K8WE to 9014 byte frames.

Dlink gaming router DGL-4300
X7DWA-N
CAT 6 Plenum Grade solid wire backbone

Dlink DGS-2205 switch
Thunder K8WE
Fedora 7 web server
CAT 6 Plenum Grade solid wire backbone

Everything is CAT 6 and 1 Gbps. Vista reports 44 MB/s when copying 100 MB+ files. I am adding a DGS-2205 on the DGL-4300. The DGL-4300 does not support jumbo framing. I found how to do it in Fedora 7. Set MTU=9000 in a network file. I was expect closer to 70-80 MB/s. The Dlink DGS-2205 has a 10 Gbps fabric switch. I might put Intel server NICs in each workstation and server to match frame size. Any other suggestions?

Looks like you got it all covered...Just remember if it reports 44MB/s copying files the real throughput will be 88MB/s because its reading/writing the files, so dubble any reported speed.

You can check this from the Performance Manager in taskman or Performance tools in control panel

Perfmon matches that figure. I did get it up to 65 MB/s.
