Hello
just to update this thread
I setup OpenBSD 6.6 Release on Proxmox 6.1 with an intel 82599ES 10G nic
physical function pass through and there was no issues with jitter at all..
so that throws my SR-IOV / PCI Bridge issue theory out the window...
so the jitter issue seems to be an issue with
Hello,
from bare metal testing the ixl driver didn't have any jitter, but when IXL card
it was passed through with SR-IOV on a KVM virtual machine
there was jitter,
so i'm thinking the issue is in the virtual machines handling of the
PCI-PCI bridge
I'm assuming based on the above test
the iavf dri
Hi,
I ran another test with virtio net drivers on the same Q35 type vm guest in
KVM
and the pings were a lot more stable.

Are you sure? E.g. VM (centos) on busy as hell Proxmox instance:
# ping -c 5 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

Hi Joseph
Thanks for your email and suggestion
Basically the vm is running 2 cores of a 20 core server with only one
other 2 cote vm running
My experience would expect jitter of no more than 2 -4ms in running
openbsd on kvm where contention on cores is minimal
The virtio setup... using the h
Tom, is not the jitter you are experiencing totally normal overhead for
a hypervisor.
Someone would need to correct me on this one but I'm surprised that you
are surprised about the jitter, considering it's a VM.
Please run OpenBSD on bare metal??

just to say when testing this
I was running the openbsd6.6vm with one other vm as a guest on a
proxmox 6.0 / KVM Host,
with 2x Intel 10 Core Xeon E5 v2 Xeons, with no hyperthreading on the
host.
what other tests can I run to help identify the source / cause of the
jitter
Thanks

Hello,
Thanks to Jonathan Matthew and DLG for their work on ixl and iavf drivers
and everyone else who worked on it..
One thing I have noticed in trying out this driver on 6.5+ current and 6.6
release is that while the latency is low... there is quite considerable
