I think this option sets the maximum number of queries to send
before it gets a reply and this is not per second. According to
dnsperf's help -q sets this, and -Q sets the queries per second
limit.<br></div></blockquote><div><br>Yes, you are right, but this option greatly correlates with qps, so by changing it you can get the number of qps you need.<br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
