Can you provide the whole specs of your servers? And also firmware version on NICs?

What firmware version installed on your NICs? Did you try to upgrade/downgrade firmware? It's the only idea that I have at the moment. I will try to test too.

What NICs do you have?

.13 has the same issue.

I have MCX311A. Did you try to resolve it somehow without rollback? I tried .12 with no luck, will try .13 today.

Thanks for the reply and for the help, but in my case I'm not using ZFS at all... By pools are BTRFS pools. Anyway, thanks for checking and for help.

After downgrade to 6.12.10 speed improves instantly: pv /mnt/user/Test/image.img > /mnt/remotes/192.168.1.1_Test/image.img 51.9GiB 0:02:17 [ 385MiB/s]

I made some tests. First one is SMB, second one is NFS. Very poor speeds for NVMe to NVMe transfer. NFS is slow even for HDD. pv /mnt/user/Test/image.img > /mnt/remotes/192.168.1.1_Test/image.img 51.9GiB 0:04:30 [ 195MiB/s] [======================================================================================================>] 100% pv /mnt/user/Test/image.img > /mnt/remotes/192.168.1.1_Test/image.img 51.9GiB 0:05:22 [ 164MiB/s] [======================================================================================================>] 100% So seems not to be related to SMB.

I will try to test with a NFS mounted share, also I will try to test with a Windows PC but it's unlikely that it will hit 10G due to PC hardware limitations.

Can it be related to SMB and/or UD plugin?

Well, I don't see what can affect it either. There were no any configuration or hardware updates for months (or even years), servers just working and I do not touch anything. But the strange thing that I had this issue twice and both times right after OS updates... Any ideas what else I should to check?

I'm using Mellanox ConnectX-3 MCX311A.

I've checked multiple things. Network seems totally ok (almost 10G between servers in both directions), SMB/Network settings was not changed for years and seems ok too. Router, switches are totally ok. So this thread is my last chance to resolve this issue. Thank you anyway.

I forgot to mention that I got 3 servers on Unraid and problem exists on the all of them.

Already done this before opening this thread, speed improves instantly.

Yes, on the 6.12.10 performance is great, I hit 700-800 megabytes per second. The strange thing is that on the 6.12.9 I had the same problem but it was resolved on the 6.12.10 (there was a some rollback in the change list of the 6.12.10). Can it be a reason?

Hello. After an update to the 6.12.11 I got an issue with slow SMB share speeds. For example, I have a nightly backup of my Windows VM, it's about 100 gigabytes. On the 6.12.10 it took about 4 mins every night but after an update it always took 7-8 mins. Which a lot slower than before (NVMe to the NVMe transfer, 10G network). Average speed is about 300 mb/sec, before it was 600+ mb/sec. I had this issue on the 6.12.9 as far as I remember, but after an update to the 6.12.10 it got resolved somehow. Any ideas why this is happening? No hardware or software, network, etc configuration update was made. Iperf3 result is 9.4G in both directions. Here is the network graph on the 6.12.11: Graph on the 6.12.10:

After update to 6.12.2 I have warning "Possibly out of inotify watches". Using Tips and tweaks plugin I changed setting, but the warning is still persist. Current settings: Max User Watches = 8388608 Current User Watches = 6085403 Available User Watches = 2303205 Also I never had this warning before. 6.12.2 bug?

But a lot of things is not quite good and reliable yet. SAS drives spindown was broken ages ago and not working still, technical support is very limited (most of my questions I resolved by myself, no one helped me from the community), many OS features is a third party plugins which can stop working or being updated at any time, etc, etc, etc. But from 3.5 years of Unraid experience, it's ok. No need to migrate for me to anything else right now. But it's become a little annoying that every major update focuses on cloud services like MyServers or Connect. From the past 2 years, only Pools and ZFS was added (big features)? Not so much. And security updates were very rare. Also I have concerns that Unraid will require in the future active internet connection and Unraid online account and authentication working 24/7.

Ok. This is the answer I was looking for. Thanks. Moderators, please close the thread if you prefer. Personally I prefer VPN for administration as it's one of the the best practices. Proxy only for services like Nextcloud, Plex, etc. For many of users, agree. But it's relies on the end user. For me, it's not a big deal, use only official service or the one which you hosting by yourself. Do not use service you don't trust. I have tried it long time ago and it was a disaster. API was failing multiple times a day and I have to disable it because it didn't seems reliable at that time. I know it was a beta, but still.

Rude. Moderators, please check. It's a violation of forum rules. And it's bad. Why not make a selfhost alternative? I'm not talking about making it opensource. Just an ability to selfhost. You can selfhost Omada, you can selfhost Ubiquity. It's the same. Not only beginners use Unraid. There a lot of qualified engineers here. Since I paid for Unraid 3 times, I want to use it. Please do not decide what I want or don't want. P.S. If you don't understand my point, please stop spamming me. Don't waste my time if you have nothing to say about discussion. It was a question to Unraid developers, not for a "community".

And it's bad. I have 3 licences and new features are not suitable for everyone. There are no freedom here.

Please send me a link how can I selfhost Unraid Connect. Also do not confuse one with another. Reverse proxy, Google Drive? It's does not apply to Unraid Connect and it's not an alternative. Also setting up reverse proxy on server dashboard? It's insane in the matter of network security. Use VPN instead. I want to selfhost Unraid Connect. Like a dashboard for my servers. A good example with networking. You can selfhost Omada or Ubiquity controllers, why not Unraid Connect?

I'm not sure what you mean by this, but you don't get my point. Please re-read the original post. My point is to let an ability to selfhost Unraid Connect service and to not force people to rely on third party clouds. Many of us don't trust clouds (even if cloud from Unraid developers) and want to control everything. If you want to use Unraid Connect, you don't have options here and you have to loose some control over your services and data. I think it's not a big deal to publish a docker image or a VM image in the future and make some freedom to those who don't want rely on third party cloud services (which Unraid connect is, basically it's a cloud service).

The whole point (for many of users) of hosting a server at home (work, etc) is to using selfhosted services, manage data locally and to not send it everywhere and to everyone, etc. Is there a option to selfhost Unraid Connect? Or will be it planned in the futute? Many of us want to manage data by ourselves and do not trust to third party people or services in matter of data - this is the basis and the whole point of selfhosting. Also many of us have a lot of skills and can easily deploy such kind of service on VPS, on another server or somewhere else (I mean Unraid Connect) and configure network for secure access. For now we do not have an option to use best practices in security and privacy for Unraid Connect. For example with networking technologies, you can selfhost TP-Link Omada controller or Ubiquiti controller, why not Unraid Connect? Regards, Unraid user.
