DL185 G5 poor Ethernet lan speed

I picked up this server for like $20 and just using it for my homelab setup. The problem is that the ethernet speeds are peaking at 8MB/s on the LAN and even worse to the internet down to like 5MB/s. This would normally point to being connected at 100Mbps but both server and router are reporting a 1000Mbps link. This is both pulling to server and pushing out which rules out drive speeds. Plus testing on SSD. My computer will do gigabit speeds connected to same router. I have used the same cable on the server with no change. Running Proxmox on Debian with kernel 5.3.18-2-pve. Any ideas or suggestions would be greatly appreciated

I can run this for however long I want but this is exactly the same issue. I seems like somehow is locking to 100mbps no matter what the router and server say link speed is
