The Dhrystone should be a better representation than the Whetstone though. Moreover, some highly complex application program (VLSI routing for example) would serve as a good test case. It's important to make sure the operating system doesn't affect the benchmark. Both the CPU and the OS version should be the same (i.e. the same implementation of UNIX). Since I doubt 4.2BSD runs on the 386 yet, how about System III or V? Remember - Benchmark the CPU, not the UNIX implementation.
