Which Dhrystone version? 1.1 oder 2.1? This is important!

The TT we tested calculated a new move in our mill game in a bit more than a
quarter of the time it took on the ST. The cache was enabled, and everything
ran in slow RAM. As strategy game move searchers are extremely CPU-bound,
this should be interpreted as a kind of upper speedup limit for real-world
applications that aren't recompiled.
