  17. SUMMARY:  More Benchmarks for SAS under OS/2
  18. E-ADDR:   ADROSEN@vms.cis.pitt.edu

  22.  
  23. I have some benchmark results to add to what Joe Svec provided for SAS under
  24. OS/2.
  25. I have included below:
  26.   1. Table describing the computing environments.
  27.   2. Table of comparisons.
  28.   3. The benchmark program.
  29.  
  30. Please note that one of the tests includes results for two sessions which were
  31. run almost simultaneously. After submitting each session in sequence,
  32. I opened up OS/2's Window List so that neither SAS session had
  33. any preference by the operating system.
