Re: how is system geared down?

Nathan,

I must say that this is the most lucid and believable explanation that I
have ever heard about component vs system performance.  I've heard, in
the past, about component speed synchronization problems and this may be
the universal governor that cures that ill.

I hope you don't mind, but I'm going to borrow this.
