IBM Notes and Domino (formerly Lotus Notes and Domino) are client and server components, respectively, to the popular business collaboration system. While Notes and Domino may perform well within the office, performance may suffer across distance. Notes and Domino databases may fail to open and files may take too long to transfer. Notes clients may be unresponsive and connection failures may occur as the network is occupied by other applications. Adding more bandwidth alone will not solve these problems as they may also stem from the latency and congestion of the WAN.
