Dual 10Gbs iscsi caps at 1.6GB/s

If you make any progress, please update this post.
I have a 100Gb network interface and I am also limited to 1.6 GB/s.

Now switched to Proxmox instead of Truenas barebone, still getting 1.6 GB/s (which is expected) but I am testing Vanilla Ubuntu right now and there I see speeds of 8-10 GB/s with the same hardware.

Most people just tell you to buy more expensive hardware to solve the issue or are just saying your use case is invalid. It’s a pretty toxic community albeit there are some great people as well.

Without having any deep knowledge, I think there is a limitation with the network stack they are using.

My specs:

Supermicro H12SSL-NT-O
AMD Epyc 7313
128 GB Kingston 3200 MHz ECC ram
8 Samsung PM9A3 U.2 7680 GB SSD’s

I strongly disagree. People coming here, posting for the first time and throwing mud over the community because they are not getting a reply (or their desired reply) is toxic.


Running ZFS?

Yes, just using PCIe passthrough off the same pools used in TrueNas Scale.
Used Cockpit for creating the SMB shares.

While I do understand your opinion, it’s just not true, the mud is already all over the place. You saying that the opinion of someone new is less valid is exactly the problem, people can read for years without reacting.

People that ask questions about VM capabilities or issues that get wrecked because TrueNas is not a Hypervisor (but still used it in their marketing…). Network not fast enough? Must be bad hardware. People then prove over and over again by going through hoop after hoop that the issue is not hardware related but still it’s ignored.

I actually started using TrueNas Scale for the Kubernetes implementation. Must admit I was disappointed that there was no good backup or HA system and they are now removing it completely. It had it’s fun moments but has broken so many times that the maintenance was just getting too much. It seems that they are not sure which direction they will go and it’s hard to sell it as an enterprise product this way.

I never wrote as such though? I totally agree that people can just read and learn without registering and account; actually, being able to do so is one of the most important things for me.

Yup, and that’s iX’s issue. The community having a different opinion is legit, don’t you think?

I agree with this and most of your post, as most of the historic part of the community does in various degrees. The posts, both on this and the old forum, are free for anyone to read.


It’s something worth investigating, please consider opening another thread and reporting your testing.

As a matter of fact I am unable to directly help @Antonis_Marcou due to my lack of knowledge; I joined the discussion to point out a few non-technical things.
