Help with Proxmox 7.2 and LXC Network Please

[AnThRaX]

Hey all, just setup Proxmox and an Ubuntu LXC for some containers, my NIC is an Intel Corporation I211 Gigabit Network Connection (rev 03). At first my speeds were fine, then I'm not sure what happened, but now it's so trash and bogs down so much that I can't even control things via CLI. I have gigabit internet, 940+ down, 40 up, I came from unRaid and could download all day long at 108MB/s. When I first got my Prox and LXC setup, it did the same for a brief period. Then all of a sudden it's just BLLLEHHHHH to almost a complete halt, to the point that apps and such crash out.

I haven't been able to find if the NIC is actually supported in Prox, and I'm quite new to this so I wanted to reach out for help. I've literally been up over 30 hours toying with this thing trying to get it to perform correctly. Any info you need me to provide I'm more than willing. I'd just like to get this thing stable and running at proper speeds!

Hardware:
ASRock x570M Pro
AMD 3900x
64GB Ram
14x 6TB EXOS HDD's running in RAIDZ2 in a ZFS Pool
250GB Samsung NVME SSD being used for a Cache drive
Proxmox installed on 2x 1TB SSD's running in RAID1
Thanks in advance!!

You could verify with a fio benchmark that your storage isn't the bottleneck, with a iperf3 benchmark that your network between host and LXC isn't the bottleneck and with a speedtest-cli benchmark that your internet isn't the bottleneck.
Rebooting your routers and switches sometimes also help. And you could try to boot into an older kernel in case you think that a PVE upgrade might caused some driver problems.

A friend that was trying to help me figure out the issue ran all of the tests that you are recommending, aside from booting into an older kernel I believe. The speeds from the host and the lxc for the cli speed tests were both garbage. 30ish down max and 10 up, never consistent. I factory reset my router and set up everything from scratch. Last speed test on my windows machine after that was 987 down and 41 up, 11 ms ping. The speeds between host and lxc are as garbage as the speed tests were. Disk speeds were all good, he tested all 14 of them and the nvme.

Forgot to mention also that my raid controller is a Genuine LSI 6Gbps SAS HBA LSI 9211-8i (=9201-8i) P20 IT Mode ZFS FreeNAS unRAID. If that makes a difference.
