msmq

I am trying to find where lies the bottleneck of a C# server application which underutilize CPU. I think this may be due to poor disk I/O performance and has nothing to do with the application itself but I am having trouble making a fact out of this supposition. The application reads messages from a local MSMQ queue, does some processing on each messages and after processing the messages, sends out response messages to another local MSMQ queue. I am using an async loop to read messages from queue, dequeuing them as fast as possible and dispatching them for processing using Task.Run to launch

My original question from a while ago is MSMQ Slow Queue Reading , however I have advanced from that and now think I know the problem a bit more clearer. My code (well actually part of an open source library I am using) looks like this: queue.Receive(TimeSpan.FromSeconds(10), MessageQueueTransactionType.Automatic); Which is using the Messaging.MessageQueue.Receive function and queue is a MessageQueue. The problem is as follows. The above line of code will be called with the specified timeout (10 seconds). The Receive(...) function is a blocking function, and is supposed to block until a

Can someone please help me find some sample code to SEND and RECEIVE Multicast messages using MSMQ using any .NET language of your choice. I have searched around and kind of see the send being: MessaegQueue topic = new MessageQueue("formatname:multicast=234.1.1.1:8081") topic.Send("Hello out there") I tried to do the same idea with Receive: MessageQueue topic = new MessageQueue("formatname:multicast=234.1.1.1:8081") topic.Receive(); but I get nothing. Can anyone show some sample code on how to receive multicast messages? or am I sending them wrong? So I figured it out. To send a multicast

I'm sure I'm not the first to say it, but there's a severe lack of documentation on the finer points of Service Bus 1.0 for Windows Server out there... I'm hoping some of the MS insiders can help clear a few things up... Do services utilizing queues/topics run in an implicit, ambient transaction? For instance consider the following code snippet: [ServiceBehavior] public class MySbService : IDoWork { [OperationBehavior] void DoSomeWork(WorkRequest request) { DoDatabaseWork(); DoMoreDatabaseWork(); } } In the above sample, without creating an explicit TransactionScope , would DoDatabaseWork() be

I'm looking at MassTransit as a ServiceBus implementation to use in a web project. I am playing with the Request/Response pattern and am seeing a long delay between the consumer receiving the message and responding, and the request publisher handling the response; sometimes, it seems like the response is never going to come through (having left it running for 10 minutes, the response has still not come through). the only times that I have seen the handle delegate get called with the response is after a 30 second timeout period and the timeout exception being thrown; in this situation, the

We are migrating to Windows 2008 R2 Standard and will be using a Microsoft Clustering (active-passive) configuration. Our application is heavily dependent on MSMQ private queues and our install creates well over 100 private queues using the following C# code. MessageQueue.Create(".\private$\myqueue", false); Since the install is not running inside the context of the cluster, the queues are created on the local node and not in the cluster. We then tried changing the code to: MessageQueue.Create("MYCLUSTERNAME\private$\myqueue", false); However, you can't create private queues on a different
