Message-ID: <1638@neoucom.UUCP> Date: 18 May 89 13:53:10 GMT References: <2134@iitmax.IIT.EDU> <5625@microsoft.UUCP> <5664@microsoft.UUCP> <2962@rti.UUCP> Organization: Northeastern Ohio Universities College of Medicine Lines: 19 The dhrystone benchmark normally doesn't make calls to hardware-specific devices, as dhrystone is supposed to compile and run on virtually any machine. A 2:1 difference in the dhrystone/sec between msdos and os/2 is suspicious. One might want to inquire about what compilers were used to generate the code run in the mips magazine test. I have seen close to 2:1 differences between Microsoft Optimizing C 5.0 and the Green Hills or Phar-Lap compilers for msdos. The former was emitting 16 bit code, while the latter two were emitting 80386 code. To the best of my knowledge, the C compiler included with os/2 developemnt system generates only 16 bit code. How this applies to the Amiga, I'm not sure... Bill wtm@impulse.UUCP
