COM server-side objects must be as small as possible. If the server objects are small, their load time will be short and the client will experience a good response time from the server. Remember that the memory footprint is small for small objects. This should be an important design-time consideration for COM servers, because they can be instantiated by a large number of clients. It can affect the overall scalability of the application, especially when not using the MTS environment to run the COM servers. In such cases, this may result in large memory footprint on the server as well as a sluggish response.
