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