WCF4 streaming+routing performance RRS feed

  • Question

  • Hello!

    I try to test an ability and performance of netTcpBinding streaming through routing in WCF4. I have two servers, router and client. Servers have 2 services: one for buffered transfer and another for streamed transfer. I test it on my local machine.

    When I transfer big files directly between client and server and measure chunck sizes while processing the incoming stream, they appears to be 64Kb. Files are transferred somewhat fast. When I transfer a file through router, I get almost 70% CPU consumption on two-core machine and chunks appears to be 384 bytes. Files are transferred much slower.

    I can send source code if you'd like.

    Please can you tell what could be a cause of performance decrease and especially CPU comsumption?

    Thank you!

  • Hi,

    As I mentioned in this thread, routing service will relies on MessageFilter implementations that are used to match specific values within the messages to be routed, so I will impact the performance.

    And you may enable performance counters or the tools I suggested in that thread to help you gauge your application's performance.

    Best Regards.

  • I believe MatchAll filter shouldn't affect performance any way.

    And of course, my question was not answered. My question was about size of streamed chunks as I can see them while reading stream from WCF channel. I guess that was the cause of poor performance and high CPU load.

    Please mark your reply as not an answer.
