So I have unbound running in a vnet jail. Doing a lookup with `host` is
pretty responsive, but Chromium's lookups are extremely slow (taking around
30 seconds to resolve). I'm running pretty much a stock config. I've tried
turning off DNSSEC, but that doesn't help any. I have num-threads set to 4,
though I have 8 cores on this box. I've pasted my config below.
get a Ktrace of the unbount process along with a a matching
simultaneous tcpdump of whatever interface your packets are coming in
through. by matching the incoming and outgoing packets with the
socket activity, you should be able to isolate what component is
taking all the time.
Thanks,
