Computer performance professor just showed us this, so I had to try it out with newer versions.

Slowest to fastest:
ruby 1.8: 0m26.671s
python 3.2: 0m8.979s
python 2.7: 0m7.676s
ruby 1.9.1: 0m5.610s
Lua 5.1.5: 0m5.074s

ubuntu 12.10, intel sandybridge i5-2500k quad-core 3.3GHz(i think), some fast ddr3 ram, all interpreters located on sata3 ssd.

On my debian sid:

Ruby 1.8.7: 32.65s
Ruby 1.9.3: 5.85s
Python 2.7.3: 11.06s
Python 3.2: 11.89s
Haskell (no opt): 62.57s
Haskell (Compiled): 3.58s

So ruby 1.9 *is* fast.

Python on PyPy did this in 4.074s and in 17 secs on the same machine. Ruby did it in 10.5.

I’m happy to see Ruby getting some much needed optimization.

With jruby experiencing a speed up of about 200% thanks to invokedynamic in java 7.02 is time to rewrite the comparison.

Btw, that means 0.586306 seconds, what is more than 20 times faster than Ruby 1.9!

A honest Haskel comparison (same algoritm), but it can be a lot faster (as shown by Twey).

fib :: Int -> Int
fib i | (i == 0) || (i == 1) = i
| otherwise = fib (i-1) + fib (i-2)

fibSeq :: [(Int, Int)]
fibSeq = [ (i, fib i) | i <- [0..36]]

Slim:Desktop jorrit$ ./fib

Python 2.6.2 is faster and really faster with psyco:

On a Intel Core i7 940 (2.9 Ghz) :

16s for python 2.6.2 without psyco
0.9s with psyco !!!!!
