Hitting 1GB/s with Win10 to Win10 with Intel X520-DA2. But only 112MB/s with TNC

Tested file xfer with Win10 to Win10 using Intel x520-DA2 and getting 9000 mbps. Installed TrueNAS Scale on one PC and getting 240 mbps.

So I know the switch (Aruba 3810) and the SFP+ BiDi is all good.

Ryzen 5500
32GB RAM
Asus Prime B550 MB
1TB Samsung NVME pool (3x)

Sorry that should read ~800 mbps and not 240.

How are you exactly transferring?

Win10 to Win10 SMB. Win10 to TrueNAS SMB Dataset.

Storage pool is RaidZ1 3 wide.

I just chucked in a Solar Flare SFP+ NIC and it’s fine… Hmm.

6

I’ll try the x520 in another slot

7

Overheating? May be try some active cooling?

8

Are there more then one nic in your box? If yes did you bind the smb service to the IP of your 10gig nic?
Sounds a lot like the smb service is using a 1gig connection

That’s a thought.The Solar Flare does use about ~ 1/2 the wattage. I just wanted to start with a build that everyone says is the gold standard.

Been using used Solar Flare for years for my DIY builds. Figures first time step off the path…

I put in a Solar Flare NIC and am currently maxing out my wire speed.

Do you have more than one network cable attached to and configured in the server?
A screenshot of your Network page from TrueNAS would be great.
