I'm not sure about your question, but you could use the code I'm pasting below in a timer that executes every so many minutes to keep memory usage lower. If you're using C# and will test it out you'll see how much it saves.

                try
                {
                    Process process = Process.GetCurrentProcess();
                    process.MaxWorkingSet = process.MaxWorkingSet;
                    process.Dispose();
                }
                catch { }
