I am trying to assemble a set of publicly available benchmarks to run
on UNIX/386 machines.  I am starting small.  I got copies of Dhrystone,
Whetstones and Linpack from NETLIB.

Here is the problem:

Running dhrystone 2.1 (c version) on a 486 machine running ISC 2.2, I
get all kinds of crazy results, with Dhrystone ratings ranging from
3000 to 16000 in different runs.  The same machine under DOS, running
the Drystones version in QAPLUS rates (consistently) at 15172.

Question:

Is this normal?  Is the hardware or software flaky?  If I time the run
with Sysv's "time", user time also show the same wide variation.


Suggestions appreciated.
