Hello, Running 6.5 Stable and 6.5 Current 5/07/2019 on a Proxmox 5.3 VM,
if you are running avm with a virtio NIC and an SR-IOV ixl nic (40G Intel nic) attached you can encounter pretty severe jitter on pings to and from the ixl NIC, i.e. minimum ping of 0.390 ms and then it can jump to 55ms, up to 400ms very regularly >30% of ping responses suffering high jitter, removing the virtio NIC (which was intended as a management device only) improved our jitter considerably. with only 12 abnormal pings out of 652 pings, --- ping statistics --- 652 packets transmitted, 652 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 0.141/4.107/428.184/30.197 ms I hope this info helps other OpenBSD SR-IOV users... -- Kindest regards, Tom Smyth.
