> We are evaluating the NMS-API to connect a C# app to our ActiveMQ broker. For this we wrote a simple client which sends a request and waits for a reply (Client --> Broker --> Server --> Broker --> Client). The client/server C#-app runs in a single process with two different connections to the broker which resides on a  different pc on the network.
> This scenario takes about 200ms for each message transfered by the C#-API and less than 20ms by the Java-API although both do the same thing. 
> After looking through the code I found out that the NMS client does not use the TcpNoDelay-Option during the wire negoation. I changed the code so that this option will be negotiated with the broker and set on the underlying socket and now I have apperently the same performance as with Java. I attached the code change as patch to the current trunk version of the .NET-client.
> We would be happy if someone could check the patch and give some feedback.
