In the system that I tested, results were different.
*************
System was
CPU: AMD Phenom(tm) 9950 Quad-Core Processor, Frequency 2600MHz, L2
cache 512KB
Memory 3164MB
OS: Ubuntu 8.10
When I tried this benchmark for the first time,
id at pc:~$ time python bench.py
real 0m0.010s
user 0m0.008s
sys 0m0.000s
id at pc:~$ time ruby bench.rb
real 0m0.108s
user 0m0.000s
sys 0m0.004s
Python was faster than Ruby 10 times!!
As I repeated, results showed shorter times and became stable.
After a few repeat, stable results were
id at pc:~$ time python bench.py
real 0m0.010s
user 0m0.008s
sys 0m0.000s
id at pc:~$ time ruby bench.rb
real 0m0.004s
user 0m0.004s
sys 0m0.000s
Now, Ruby is faster two times.
Have you repeated your benchmark?
Your results looks to be over-exaggeration even if this benchmark is fair.
