Hello Bruce,

we're (@ Men & Mice) not aware of any issue with Ubound that would be
the cause of such a slow down between version.

Steps to troubleshoot this:

* check what the Unbound statistics are saying (total.requestlist.max,
total.requestlist.exceeded, num.answer.rcode.*)
* check the Unbound logfile/syslog for any warning/error messages
* use the "perf" tool that is part of unbound to have an alternative
source of the testing data

You can also send the Unbound configuration and statistics output to
"support at menandmice.com" for inspection (please let us know the CPU and
memory configuration of the machine).

Best regards
