.. _Performance: ************************** Performance Considerations ************************** This section discusses performance when using PolyORB. Many elements can be configured, :ref:`Building_an_application_with_PolyORB`. By carefully selecting them, you can increase the throughput of your application. We review some parameters that can impact performance. * **Build options**: * For production use, you should not build PolyORB with debug activated. * **Tasking policies**: * You should carefully select the tasking policy to reduce dynamic ressource allocation (tasks, entry points, etc.). :ref:`Tasking_model_in_PolyORB`. * **Transport parameters**: * Setting `tcp.nodelay` to false will disable Nagle buffering. * **GIOP parameters**: * Setting `polyorb.protocols.iiop.giop.1.X.locate_then_request`, where `X` is the GIOP version in use, to false will disable `Locate_Message`, reducing the number of requests exchanged, * Increasing `polyorb.protocols.iiop.giop.1.X.max_message_size`, where `X` is the GIOP version in use, will reduce GIOP fragmentation, reducing middleware processing.
