I Ran the test using 1 gb settings see the results below. What do you think I need to do to improve this

Specifics of my Server and network

Motherboard Asus Z87 WS
Memory 16 Gb
Raid Card LSI Megaraid 9271-8iCC with 12 Seagate 3TB drives in Raid 6 with CacheCade Pro 2.0 with 2 SSD 120GB ea
Router Asus AC3100 - RT-AC88U with the 2 Network ports on the motherboard teamed thru Server 2012 R2 and the Router set up to team.


Does anyone have any suggestions on how to improve my speed??

Well Had server hooked to the wrong ports on the Router!! Here is new test results with jumbo frames off

Iperf, there are java GUI if you don't want to run it off cmd.

I haven't use the lan test software, but a 1gb packet doesn't seem to sound right?

Use some disk benchmark and you can get how the array perform.

Personally, I recommend the following.

1. Create a virtual Ramdisk on your server (2gbps link) and a couple target machines (1gbps links) using the program of your choice (I prefer imdisk). The size of this ramdisk could be 8GB or larger on your setup.
2. Share the server's ramdisk on your network as a windows share.
3. Create a large random file that occupies half of the ramdisk on the server.
4. Map the shared ramdisk as a network disk on the target machines. Concurrently download a copy of the file on each target machine's ramdisk.
5. Repeat in reverse to test upload (you should see symmetry on LAN).

This should provide maximum network throughput.
I have had great results at reaching my network's "top speed" this way.
Best of luck.

These are some good ideas.

I would also just run some crystaldisk benchmarks or as ssd or something on both your server and your workstation to find out what the raw performance is. Then disable any teaming/aggregation and do a network speed test from the workstation to the server. I am assuming you have nothing else going on in between those two devices? Something is bottlenecking your speeds.
