 I have a 286 clone with a 80286-10 processor running at a clock speed of
12MHz.  Running the Landmark Speed Test indicates that its equivalent to a
IBM AT running at 16MHz!  Why?  How does it get the extra thoughput, or can
a processor 'fool' a performance tester?

 I also get interesting results when measuring Dhrystones against a 386SX.
The 286 measurement is 3,034 Dhrystones, while the 386SX at 16MHz is only
2,845.  The measurement software in this case is called QAPLUS.

Can these measurements be trusted?
