Performance considerations

When the Order and Quote Capture Integration is enabled in an Elite starter store, several restrictions and implementation specific alterations are introduced for achieving an optimum performance.

The Order and Quote Capture Integration framework in an Elite starter store is required to reflect the price and inventory availability status values from the databases of an external system. This is achieved by making outbound web service calls from WebSphere Commerce to the external system. Frequent outbound calls can introduce performance issues and hinder a smooth user experience. Several features of Order and Quote Capture Integration aim at minimizing the performance overheads.
