Unbiased benchmark

Dear sir,

I would like to share a benchmark I did. The computer used was a
2160MHz Intel Core Duo w/ 2000MB of 667MHz DDR2 SDRAM running MAC OS
10.5.6 and a lots of software running (a typical developer
workstation).

Python benchmark:
HAMBURGUESA:benchmark sam$ echo 1+1 > bench.py
HAMBURGUESA:benchmark sam$ time python bench.py
real 0m0.064s
user 0m0.049s
sys 0m0.013s

Ruby benchmark:
HAMBURGUESA:benchmark sam$ echo 1+1 > bench.rb
HAMBURGUESA:benchmark sam$ time ruby bench.rb
real 0m0.006s
user 0m0.003s
sys 0m0.003s

Can you believe it? Ruby is 10 times faster than Python.

On a side note, when I subscribed to the Python mailing list, it took
less than 200ms before I got the confirmation email. For the Ruby
mailing list, it took over 9000ms! Which is 4500% less performant!

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@pc:~$ time python bench.py

real 0m0.010s
user 0m0.008s
sys 0m0.000s
id@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@pc:~$ time python bench.py

real 0m0.010s
user 0m0.008s
sys 0m0.000s
id@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.
