Something that we implemented for our Data Access Layer to improve performance with UniObjects.NET was a custom connection pool (before IBM released connection pooling in UniObjects.NET) and in that connection pool, all the idle connections were kept active for a specified time, and had a "heartbeat" that opened a specific file and read a record from it every few seconds..
It worked quite effectively, but we have now updated to using the IBM connection pool.. the theory however remains.. Build a controller that handles the opening, allocation, un-allocation, idling, reallocation and closing of a connection to the backend. Then the process would be as simple as requesting a "new" connection from the Controller, which would either create a new connection, or allocate an existing but idle connection. Then when you are finished with the connection, you relinquish control of that connection back the Controller, which idles the connection for a specified amount of time for easy reuse before closing it if it is not re-requested...
