Hi,
I have a strange issue with my network on Proxmox 7.
When I use iperf between a connected PC and the Proxmox host, I get around 920-945 mbit/s.
Between the Proxmox host and a linux VM, I get 3-7 gbit/s. (everything correct so far)
But between the connected PC and the linux VM, i get only 600-780 mbit/s (most at the time 745 mbit/s).
With reverse option the result is the mostly the same with minor speed differences.
I tried it with the onboard RTL8111 nic, the pcie intel nic and usb nic --> same result
I tried it with the Pc directly connected to the Server instead of a Switch --> same result
I tried OVS instead --> same result
I tried different network vm adapters --> same result
I even tried it with different network adapters for the connected PC (Intel onboard and usb)
For configuration: It's very simple. Just stock install and I added the all the nics to vmbr0 (I also tried it with just the onboard nic connected).
Where is the problem?
I used ESXI before (no problems with network speed there), but want to switch to Proxmox because cpu idle does not work correctly and I can't use the Realtek nic on ESXI 7.
