I've been using a dual Pentium-133 system for a few years now. At the time I built it, a P-200 was the only way up and way too expensive, buying a second P5-133 and a dual-cpu board was significantly cheaper, giving about the same performance (I roughly get a maximum 1.8 times speed increase.). The machine is mainly used for compilations and for that it really speeds up things. There's some psychology involved: If you start a huge job on a single cpu machine, you can feel it slow down, while on a SMP machine you won't notice it, because you only use one cpu at a time interactively, the second cpu being busy or not is hardly noticeable. So, SMP feels faster, because it doesn't slow down - even when a single cpu system would give you more performance, but its performance varies more.
