| Algorithm is exponential - very bad. It is just meant to exercise the CPU a bit and | |
| to see what happens with different languages. Not representative of real code. | |
| Interesting that Java beats C, thanks to HotSpot. I expected Swift to be as fast as C | |
| at least. I also expected the compiled Swift to be faster than when run as a script. | |
| A bit disappointed, but more time needed to see where the bottlenecks are. Plus I | |
| need to run some real code for benchmarking. | |
| Update: swiftc -O improved the speed quite a bit to be about the same speed as Java | |
