[comp.os.minix] Dhrystone results

zemon@felix.UUCP (Art Zemon) (04/09/87)

I ran the Drystone on my Z151 with a 5MHz V20 chip under
Minix and got a whopping 162 dhrystones per second.  I also
ran it on an IBM AT and got 767 d/s.  Not exactly blazing
but then I never figured Minix was an ideal number
crunching system.

Exercise 15:
    Rewrite the C compiler to generate code which runs at
    least 200% faster....
