slow network speeds on new server.
I have been working on an issue with slow network speed with a server for a week without any success. However I dont think it is a network issue and now believe it to be a hardware issue.
On the server I have been using iperf to test to itself. I am getting results of around 45Mbits/sec. Now this is just testing from the server to itself, so it is not touching the network. After working on this for a week I reinstalled Windows thinking that it was the issue. Right after a clean install I am getting the same exact issue. Also I installed a new network card in it half a week ago, going from broadcom to intel NIC.
Any ideas on what could be causing this? Now I am thinking that it is a hardware issue of some kind? Have no idea what.

it is not related to a network issue. it is some kind of tcp stack or kernel issue.
