  31         Note that these tests are carefully designed to test performance of the underlying
  32         algorithms and not memory allocation or variable copying. As usual, performance
  33         results should be taken with a healthy dose of scepticism, and real-world
  34         performance may vary widely depending upon the specifics of the program.
  35         In each table relative times are given first, with the best performer given
  36         a score of 1. Total actual times are given in brackets, measured in seconds
  37         for 500000 operations.
