Since Proxmox 7.3 higher power usage

[Whitesnake]

I run Proxmox 7.4 on a HP 400 G5 system (i5 9500T), which is famous for it's very very low power consumption.

Since Proxmox version 7.3 I get very poor power states, it seems that something is waking up the cpu all the time. I have a second identical system (i3 9100T) where I am running v 7.1.

To illustrate the effect, here is the powertop comparison (on the left v 7.4, on the right 7.1).

I also tried to use v 7.4. on the test system (i3 9100T) and the power consumption went up as well. So it has something to do with proxmox 7.3 and higher (it could be since 7.2, I didn't test it).

In numbers: v 7.1 idle (without running VMs) uses 1.8 Watt, v 7.4 idle (without running VMs) about 3.5 Watt.

There are my grub settings:

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="pcie_aspm=force pcie_aspm.policy=powersupersave"
GRUB_CMDLINE_LINUX=""

Do you have any idea why proxmox 7.1. allows better power states (c10 nearly all the time)?

Hello, I consider this mini PC for a low-power Proxmox server but not sure whether there are still some problems/showstoppers.
Could you please be so kind and confirm whether the problem related to integrated Realtek RTL8111HSH network adaptor upload speed was resolved?

Have you managed to fix the increased power consumption problem?
Thank you very much in advance.
I hope the issues could be resolved because I really like this small PC

Speed-wise I hadn't any problems at all. Today I installed v8 and the problem persists. I looked in top and saw, that every time the power usage rises these three processes go to the top and then disappear:

pve-firewall
pvestatd
pveproxy worker

I'm not sure if these processes are responsible. Without a VM installed the system idles between 1,8 Watt and 4,0 Watt.
