Windows 2012 R2 server Bad network Performance

[jbaptista]

HPE ML350 G9 + 32GB + 6HD SAS 300GB RAID 5 With Windows 2012 R2 Server

Network Card HP 1gb 4-port 331i

I'm having a big of a problem here, my network performance is a joke on this server, i have read in the web to disable this parameters on the NIC card

Ipv4 checksum offload

largesend offload V2(ipv4)

largesend offload V2(ipv6)

Vm queues

TCP Checksum offload (ipv4)

TCP checksum offload (ipv6)

Udp checksum offload (ipv4)

Udp checksum offload (ipv6)

Done this, also disabled the Digitally sign communications and Digitally encrypt or sign secure channel data, but the problem remains. Transfering data across the local network i don't even get 1mb/s.

On windows 2003, and the workstations, i have no problem getting 10mb/s and more.

I have read that the solution goes by changing NIC to another brand. Will this solve my problem?

Any toughts?

Best Regards.

P.S Working on a 100Mbps network, it's not perfect but it's what i have to work for now. It will be upgrated soon to 1000Mbps.

Have you asked HP for help? I'd also check that the server has the latest recommended ROM bios, firmware, chipset and driver support pack.

Thanks for the reply.

Already asked HP for help, still waiting for an answer.
I run all possible updates, NIC updates, Windows updates, chipset updates.
I will try to use Smart update tool from HP, maybe a ROM BIOS would help.
Thanks for the tip.

You're welcome. I'd also ask for help with these hardware issues over here in HP forums.

Thanks for your tips, it did help.
I run HP SUM and it worked, not sure what was the problem, but it worked.

Thanks for all your help
