count-primes

These benchmarks compare performance characteristics of different programming languages. In each language I implemented exactly the same algorithm that counts the number of primes between 0 and 20000000.

The results are:

Language	Time (s)
C#	3.9
C	3.95
Intel Fortran	3.99
Delphi	4.25
C++	4.3
gFortran	4.3
Java	4.6
Scala	4.7
JavaScript	5.7
F#	6.1
Julia	13.3
Go	13.4
FreePascal	14.3
Swift	14.8
Rust	19
Haskell	20.1
PHP	52.4
Ruby	64
Python	128
Lua	148
Perl	177
Tcl	214
R	402

Using Sieve of Eratosthenes:

Language	Time (s)
Java	0.21
C#	0.39
Python	13.9
