Hello everyone,

as mentioned in the german forumm section here (https://forum.proxmox.com/threads/proxmox-super-langsamer-upload.104248/#post-448804) I have a network problem with my Intel Nuc and the Upload/Download Speed of my Nic.
I tried to transfer a Windows Server iso and its super slow, about 160kbit/s.
After a few hours its still not done.

i tried to copy/transfer it via WinSCP/FileZilla but its the same issue.

Here are some information about the Nuc:
Intel Nuc 7th Gen.
i5 7300U
Intel I129-LM network interface
16 GB DDR4 RAM
250 GB NVMe SSD

Network setup:

My client -> Switch (TP Link 5-Port 1 Gigabit) -> pfSense Firewall -> Switch -> Proxmox Host
The download speed for the Proxmox seems normal (about 100Mbit (~11.5 MB/s) from Web)

I installed Proxmox today and I´m used to it from work so I do not know whats wrong with this device/setting.
However, i could install a linux system (debian) with a linux iso without any issues.

kind regards,
 
I seem to recall that the I219 nic is not a happy partner for proxmox, if you do a forum search on i219 there are a few reports of issues.

Thanks for that reply!
I figured a few things and updated to the kernel 5.15. Now it sems that my download speed is normal:


Speedtest by Ookla Server: Contabo - Dusseldorf (id = 35154) ISP: Deutsche Telekom AG Latency: 5.42 ms (0.16 ms jitter) Download: 94.35 Mbps (data used: 47.1 MB ) Upload: 33.58 Mbps (data used: 16.0 MB ) Packet Loss: Not available.

i checked the performance with iperf3:

Get just half of the speed but still better then 300 Kbit/s. Why is the SFTP/HTTP Upload so slow?

i use a direct link from a website (WAN) via wget:

is there any reason why the SFTP/HTTP Upload is super slow on my Host?
Can i change some configuration to make it faster?

ISO uploading just became the hell with 7.1-10
==> communication failure (0)
after that , totally break WEB GUI. (ERR_TIMED_OUT)

Our server is a 128GB memory , 2 CPU => Xeon(R) CPU E5-2697 v2 @ 2.70GHz (2 Sockets) (SSD for promox system in ZFS RAID1)

I don't know if dev. at Proxmox can see how this release totally diserve the product.

Found the problem for me and a solution. It was a faulty windows 10 nic driver what made the internal upload speed slow. I had to reinstall the windows and now everything works fine.
