Dhrystone figures cannot be used to compare systems performance!!!!!!!!
Dhrystone figures are heavily influenced by the strxxx functions.
For most unix 386 systems those functions are coded in assembler with
the repeat instruction. The C compiler we use does not generate those instructions.
What I am saying is that dhrystone comparison between 386 an 680x0 cannot
be used to compare systems. You need info about other benchmarks as well.
My experience is that a 68020 unix system performs better than a 368 system
both running with the same clock frequency. ( 16 Mhz ).
