Of course you don't. But you might well get enough CPU to keep your users happy, depending on what they're doing. Also of course, the dirty little secret of the PC world is that you have vastly gross overabundance of CPU for most "real computing" tasks. Serving web pages or delivering email doesn't take much CPU. Reading email shouldn't take much CPU, although if you insist on doing it inside UltraWhizzy K/Gnome/Mozilla/MultiMediaMailReaderNowWithGratuitousAnimation!!! then it can find a way, I'm sure, to burn CPU. Still, interactive users spend most of their time just sitting around, as you show: > 53 users, load average: 0.10, 0.07, 0.05 Playing Unreal Tournament, now, *that* takes quite a bit of CPU. If you're trying to consolidate a CPU-heavy workload, S/390 is definitely not the platform for you. Adam
