I'm currently comparing the intel iAPX 286 and 386 processors with the view
to writing a real-time operating system in protected mode.

I've come accross an article which comes to the conclussion that a '286 is
as fast as a '386 (with same clock frequencies).

What are the highest clock frequencies in use for these processors ?
I'm not interested in special cases where a some huge clock speed has
been achieved in a test, etc.

--
What kind of performance improvment can be achieved using with the fastest
386 clock frequency relative to the fastest 286 ?

Any comments, suggestions, references that any of you think might be of 
interest to me will be appreciated.

Thanks,
