  8.       Performance data for Cyrix 486DLC, Intel RapidCAD, Intel 386DX,
  9.       and Intel 8086
  10.  
  11. Note: The time resolution in the ARITEST test program is about 0.3
  12.       usec, so the relative timing error can get quite large for
  13.       small times like those measured on a 386DX, 486DLC, or Intel
  14.       RapidCAD. For these processors, the times given in the table
  15.       represent the average of three measurements.
