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.
