hanoi-bench
An implementation of hanoi tower resolver in different web-related languages:
- C++
- Java
- JavaScript (Nodejs)
- PHP
- Ruby
To run all scripts launch
./run.sh [number of decks of the tower]
Each resolver prints out the execution time
My Test
I run a test on my iMac mid 2010, for a number of decks variable from 18 to 24, using these compilers and interpreters:
- php 5.5.29
- node v0.12.0
- ruby 2.0.0p645
- javac 1.7.0_71
- g++ LLVM 7.0.0
and these are the results I've obtained expressed in seconds
| # decks | C++ | Javascript | Java | Ruby | PHP |
|---|---|---|---|---|---|
| 18 | 0.0020 | 0.0040 | 0.0480 | 0.0632 | 0.2907 |
| 19 | 0.0050 | 0.0070 | 0.0570 | 0.1253 | 0.5959 |
| 20 | 0.0063 | 0.0083 | 0.0740 | 0.2385 | 1.1870 |
| 21 | 0.0190 | 0.0290 | 0.1130 | 0.5033 | 2.5338 |
| 22 | 0.0330 | 0.0430 | 0.1690 | 0.9547 | 4.8684 |
| 23 | 0.0760 | 0.0860 | 0.3060 | 2.0705 | 10.1063 |
| 24 | 0.1260 | 0.1690 | 0.5710 | 3.8711 | 20.3050 |
Javascript performance are great, not far from C++ ones. Widely used web languages like PHP and Ruby have very poor performances compared to C++ Javascript and Java.
