WCF Adapter causing more than 20 seconds delay RRS feed

  • General discussion

  • our biz talk process consume external asmx Web Service,

    the response from the web service in quite fast but once the message got received by adapter then it will take 2 to 20 seconds of time to deliver that message to Orchestration process,

    the 2 seconds time increases with the passage of time to 20 seconds

    More Details:

    --Wcf adapter is configure for Basic http binding,

    --our process use to read document in chunks using concurrent calls to the external webservice.

    --Response time from the external web service is less than a second.

    --Process is running on a Separate Host.

    --i have made changes in the host settings by increasing the

    a. worker thread upto 100

    b. Maximum I/O Threads to 350

    --Polling intervals 

    Messaging 50 and orchestration 50.

    --CPU setting 

    in process messages to 1000

    --internal Message Queue Size to 1000
