Mininova tried this [1] and got something like ~1000 MIPS out of it. That was using Firefox 1.5 though, running their IPS counter on Chromium dev on a modern Core2 duo gives me 71428571 IPS, more than a 30x improvement over the per-user numbers they cite. Back of the envelope math: ceteris paribus that would put a 3-million pageviews/day somewhere along the lines of a dual-Itanium box today. Facebook pushes ~500 million pageviews so has access to ~300 CPUs worth of computing power in the form of its visitors' javascript engines (~5,600,000 MIPS).
