[olug] Wondering if I can pick your brains on my new KVM install

[Justin Reiners]

I just recently rebuilt my home server again, it ran Korora 25, and because
they decided not to release anything past 26, I decided to move it to
Fedora Server.

I run SABnzbd, Sonarr, Radarr, many docker-compose and docker scripts,
mariadb, grafana. and some custom python code I wrote for my software
defined radio to pull my smart meter use. I also have about 11 different
VM's on KVM from windows, to Linux in many flavors for my testing.

I have a speed test script that I plot with Grafana, checking both CL's own
speed test, and fast.com, and I notice a huge difference in network speeds
since I switched to the new server.

I've tried switching the network card type from rtl8139, e1000 and virtio,
and it still seems the VM is limited to 300-400Mbit.

Running the same test on my old server, I'm able to hit 900+mbit
consistently.

Any suggestions?

The old and new server are the same identical hardware. R710, 128GB RAM,
12TB, 2.93ish GHz quad-core Xeon. The old server ran everything under
docker, or on the host itself.
