    Direct Discovery on Ajax performance Difference to Client/IE plugin

    Shawn Hicks

      I have been working with Direct Discovery against Hana and have observed the following:

       

      1.  Client uses qvconnect64.exe and fully utilizes the SET DirectConnectionMax = 20; i.e. opens multiple "pipes" to Hana.  works great!

       

      2.  Distribution service uses the qvconnect64.exe and only opens one pipe.

       

      3.  Ajax client uses QvConnect64.exe and only opens 2 pipes,

       

      4.  IE plugin uses QvConnect64.exe and fully utilizes the SET DirectConnectionMax = 20; i.e. opens multiple "pipes" to Hana.  works well but not as good as the desktop client.

       

      I also noted that when I open an Ajax session and a IT session, they appear to be not sharing the QVconnect pipes.

       

      Can anyone explain why this is happening?

       

      I need to use Ajax and also open multiple pipes for performance.
