Remember, UNIX was designed long ago, at a time when a computer that could hit one million integer instructions per second was nearly science fiction. UNIX was therefore designed to be fast, and even today, despite the gradual evolution that the OS has undergone, it still is extremely fast compared to certain very bloated operating systems that were written at a later time, when increasing hardware speeds could conceal laziness on the part of systems programmers. Given what older hardware used to support under UNIX, I wouldn't be at all surprised if you could support 1000 simultaneous timesharing users on FreeBSD with a modern PC. If you add X then you naturally gobble up resources and bring UNIX closer to Windows or the Mac, but if you run a straight text-only OS, it can be hard to ever come close to the machine capacity with any kind of real-world load (meaning a realistic load of the type for which UNIX was intended). I never seen less than about 97% idle my machine, and the average over time is closer to 99.9% idle. The machine is definitely working, but with a streamlined OS and straightforward applications that don't have to drive GUIs or play music or animate movies, it flies. -- Anthony
