Notes:
1. "--"indicates less than 1% of total time.
2. Percentages for test 9 averaged over 10 runs.
3. Tests made using a 386DX-40 processor with a 64K static RAM cache. 
   Source compiled by Turbo C v2.0 to small model byte-aligned 8088/86
   object code using default compiler options (size favored over speed).
