Unbound statistics - long recursion time

[Chris0815]

Just wondering why there are some DNS requests on my end that take quite a very long time, so 126 counts in the range of 1-2 minutes.
Is this something you also have?
Is there a way how to find these long DNS-requests to find the reason and try to eliminate it? Does it make sense to stop/delete DNS-queries after some seconds?

Thanks in advance!

As far as I understand, these stats are just for recursive lookup and do not include cached results, which should make up a majority of your browsing.

Some domains will be really far away, and with delays and retries it takes time to do the lookup. This may take a few minutes in some cases. However, since many are updated early due to prefetch, you likely do not notice any of these longer delays.
