Neither good nor bad, just inappropriate for evaluating whole system
speed.  If your desire for speed is largely to speed up number-crunching
apps, then these are what you want.  If you're evaluating suitability of
a system to run Windows 95, then they are very misleading.  The point is
that whet- and dhrystones mainly measure the speed of the CPU/FPU/cache
part of the machine, and largely ignore bus, video, and disk speed.
Thus, they make something like the AMD586 chip - which is fast
internally, but slow in talking to the rest of the world - look
artificially good.
