Funny results on programming languages performance stub test

I've just wrote a stub performance test for different programming languages and I've got fun results.

The stub summarizes all numbers from 1 to 100,000,000. The results below:

Test: C
Result (seconds): 0.29

Test: Java
Result (seconds): 0.20

Test: Perl
Result (seconds): 20.00

Test: PHP
Result (seconds): 8.06

Test: Python
Result (seconds): 27.29

Test: Ruby
Result (seconds): 83.67

Java faster than C. PHP faster than Python (why does Python have compiled files??). PHP hits Perl.
Ruby sucks as always.
