I'm using CLIENT connection mode. The XMS documentation says that it is the default connection mode for .NET. I have the same delays you had (between 4s and 10s).
I'm not sure, but I think if you ... |

1) Connection and Session performance is not a big issue for my application. I create them at the beginning of the application and close them at the end.

fjb_saper,
I did some debugging and some research on JMS. I found out two interesting conclusions :
1) The feature I implemented does not need to use Multi-Threading ; XMS sessions could do the ... |

bruce2359,
The only thing I changed is : using XMS API instead of MQ API + native RFH.
About performance :
- My Server (C++) has the same performance than before. It is simpler ; it reads mes ... |

Forget about this hypothesis :

fjb_saper,
I do not think the value of the timeout or the behavior of the form (frozen or not) have direct relationship with my XMS performance.
The problem is to know how do I use XMS stuff fo ... |

fjb_saper,
Thanks for all hints.
Check your application. Looping around a receive is not good practice.
You should set the right amount of time in the receive... (like receiver.receive(1000).

I have some performance issues in my C#/XMS application. I suspect that the reason of that performance problem is : XMS sessions wait long time before getting CPU. I did not have that slowness ... |
