Indeed, the boot seems faster than on a real 486, if my memory doesn't mislead. It of course doesn't probe hardware, but the boot messages seem to go by faster too. Perhaps not surprising: those were 66 MHz machines, and javascript emulator on a 3 GHz machine is likely faster...

Well, I got about 20 bogomips from /proc/cpuinfo when running on my laptop, but still, I agree, it feels very usable from a quick tour.

I got around 20 BogoMips as well. Did a quick benchmark with a simple shell loop and it was 400 times slower than my PC ( 4822 BogoMips ).

According to the BogoMips website 20 is around a 486DX/40 ( That is 40MHz ) which is roughly the PC I had in 1994 (running Linux).

Well, curiously I did get the same BogoMips (20.21), both in Firefox 4 and Chromium, on a virtual machine and on the host OS, which seems weird...

Seems reasonable - if there's no attempt to sync. the emulated RTC to wall time, the bogomips calculation will just give emulated instructions per tick of the emulated clock, which should be independent of the browser or host (and even more useless than normal bogomips as a performance estimator).
