Ali, I've seen those graphs before when PC Magazine was benchmarking the new 4-way Xeon servers based on 450NX. As the number of clients increases, the score (transactions per second) increases sharply up to a peak. Then the score gradually decreases as more clients are added, probably due to congestion and I/O limitations. What is interesting is that the Profusion 8-way performance curve drops off gradually right after its peak, as normal, but then drops quickly to the level of 4-way performance later on. I'm sure Compaq is very interested in this phenomenon. <A system with 12 clients only at a time is a joke, "mission critical" joke.> That's why they'll be more than one server, of course. ;-) Besides, the 12-client peak is only a point of optimal performance. The server will still gracefully handle many more clients, particularly in "burst" conditions where every client tries to do stuff at the exact same time. I would guess that these burst conditions aren't very frequent if only one server is going to suffice. In any case, the x86 8-way market is still wide open for competitors. HotRail's 8-way Athlon chipset has a lot going for it, which makes me interested and worried at the same time. Tenchusatsu
