<font face="Calibri" size="3"><span style="font-size:12pt;">
<div>Hello,</div>
<div> </div>
<div>I’m using the .NET client and attempting to get performance from using PublishConfirms. To date, I don’t see much performance over using the txConfirm model though. Hence, I’m wondering if I’m doing something wrong.</div>
<div> </div>
<div>I’m creating the Connection and Model and then calling ConfirmSelect()</div>
<div><font size="2"><span style="font-size:11pt;"> </span></font></div>
<div>Then in a tight loop, I’m publishing messages like so:</div>
<div style="padding-left:108pt;"><font face="Consolas" size="2" color="blue"><span style="font-size:9.5pt;"> lock<font color="black"> (</font>this<font color="black">.activeMessagesLock)</font></span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> {</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">var</font> deliveryTag = 0UL;</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> deliveryTag = <font color="blue">this</font>.model.NextPublishSeqNo;</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> </span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">this</font>.model.BasicPublish(</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">this</font>.exchangeName,</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> message.Header.Topic,</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">this</font>.properties.Durable,</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">false</font>,</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> messageProperties,</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> body);</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> </span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">this</font>.activeMessages[deliveryTag] = message;</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> }</span></font></div>
<div><font size="2"><span style="font-size:11pt;"> </span></font></div>
<div>On the consumer side I’m doing the following for receiving the messages:</div>
<div> </div>
<div style="text-indent:36pt;padding-left:36pt;"><font face="Consolas" size="2"><span style="font-size:9.5pt;"> consumerModel = <font color="blue">this</font>.connection.CreateModel();</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> consumerModel.BasicQos(0, 1, <font color="blue">false</font>);</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">var</font> consumer = <font color="blue">new</font> <font color="#2B91AF">QueueingBasicConsumer</font>(consumerModel);</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> </span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">var</font> consumerTag = consumerModel.BasicConsume(</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">this</font>.queueName,<font color="blue">true</font>,</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> consumer);</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> </span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">while</font> (<font color="blue">true</font>)</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> {</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="#2B91AF">BasicDeliverEventArgs</font> item = <font color="blue">null</font>;</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">if</font> (!consumer.Queue.Dequeue(3000, <font color="blue">out</font> item))</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> {</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">if</font> (<font color="blue">this</font>.terminateThreadConsume.WaitOne(0))</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> {</span></font></div>

<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> }</span></font></div>
<div><font size="2"><span style="font-size:11pt;"> </span></font></div>
<div style="text-indent:36pt;padding-left:72pt;"><font face="Consolas" size="2" color="blue"><span style="font-size:9.5pt;"> if<font color="black"> (</font>null<font color="black"> == item)</font></span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> {</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> <font color="blue">continue</font>;</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> }</span></font></div>
<div><font face="Consolas" size="2"><span style="font-size:9.5pt;"> consumerModel.BasicAck(item.DeliveryTag, <font color="blue">true</font>);</span></font></div>
<div><font size="2"><span style="font-size:11pt;"> </span></font></div>
<div><font size="2"><span style="font-size:11pt;"> <font size="3"><span style="font-size:12pt;">}</span></font></span></font></div>
<div><font size="2"><span style="font-size:11pt;"> </span></font></div>
<div><font size="2"><span style="font-size:11pt;">Unfortunately this is really slow. Is there some property I’m missing that I can use to increase performance? Since I’m setting the “multiple” flag to True in the BasicAck, I tried to call that on every 100
or 1000<font size="1"><span style="font-size:7.3pt;"><sup>th</sup></span></font> message….but I found if an ack isn’t sent, I’m not allowed to read another message off the queue.</span></font></div>
<div><font size="2"><span style="font-size:11pt;"> </span></font></div>
<div><font size="2"><span style="font-size:11pt;">Thanks</span></font></div>
