 Given the performance of CPU technology of the late 1990s, Excite and Ubique estimated that a single VP server could manage a community up to about 100,000 chatters.However to scale up to millions of users, as handled by chat systems such as Yahoo, MSN, or AOL, the single central server would have been a limitation.The Ubique and Excite developers were working on a multi-server enhancement to handle larger traffic, but the decline of Excite and the purchase of Ubique ended that effort.
