It reckons users can expect a return of up to seven times on their investment in parallel processing over a five year period – five times over two or three years. But Informix Software Inc believes customers are still far more likely to choose symmetric multiprocessing over the massively parallel variety for their high-end requirements, because the latter represent a substantial administrative overhead.
