OpenBSD strange behaviour on Vultr
I have several hosts with Vultr (kvm-based I believe), one of which is now oddly slow.
Right after a reboot, things are working fine but just 12 hours later, sending five pings take 35 seconds:
$ time ping -c5 localhost
PING localhost (127.0.0.1): 56 data bytes

Interactivity via SSH becomes prone to unusable spikes of latency. Loading files via HTTPS seem unaffected.
Sending pings from another host shows it's responding just fine. I've seen time being off by 3-4 hours as well.
Any input?
