Each benchmark has been compiled as a standalone program using the
Roadsend Compiler's optimize switch (-O), and compared against the
same benchmark when run with PHP 4.4.2. The times are in seconds.
They have been averaged over 25 runs. The test machine is an AMD
Athlon XP2800+ running linux 2.6.9
Many of these benchmarks are derived from the benchmarks used in
Doug Bagley's Computer Language Shootout

3.36258696
| 1.4853134
| -1.877 44.0% | (2.263X faster)
|
|
Julia-PPM produces a Julia set fractal in the PPM image format. The output is quite pretty. It represents complex numbers using PHP arrays. It depends heavily on memory management (object copying) performance.
|
| matrix.php |
1.57392088
| 0.78087108
| -0.793 49.0% | (2.015X faster)
