[Unbound-users] poor unbound qps completed recently

I put bind back on to rule out unbound, and am getting the same results,
so now I need to chase what is throttling that server. 

 

- not an unbound issue.

Subject: poor unbound qps completed recently

 

Hi

 

I have been trying the various flavors of unbound, testing the qps

 

Recently I seem to have been throttled (now on 1.46) threads no and
libevents yes (when I started testing with earlier version was much
better)

 

Where the queries completed bears a question - thoughts on what I have
done? 

(no Iptables for the first thought)

 

I am seeing:

 

root at wnpgmb02hbv# /usr/local/nom/bin/resperf -d
queryfile-example-100thousand 

 

DNS Resolution Performance Testing Tool

 

Nominum Version 1.0.1.0
