Can somebody post a short IDL benchmark routine that we can time? It would be very interesting to know the speeds of various workstations, operating systems, and languages. The benchmark should be run on workstations with no other jobs (except what is normally running) on the system. The IDL function systime() might be useful for timing various stages of the routine.
