were you expecting interpreted languages to beat C native code?

No, but I wasn't expecting a difference like that >>4
That was due yo a makefile I had set up for some opengl shit

you know what's even more retarded? Thinking you're gonna get a good result when comparing native vs interpreted.
Now how about you go shit on someone elses thread you faggot

The point in benchmarking is I know native is faster than interpreter, but I want to know how much, and I also wanted to compare different interpreted languages. I found the results interesting and therefore posted them. I always thought Ruby was slower than python. SCIENCE

Then if C was merely looping, comparatively, Erlang is fastand I am proud

rofl, hahaahahahaha omfg wow gg loloolol wowwww omg lolllllll so fanny lol like 1 minute faster and how long does it take to read in comparison faggot?
>>33
If you really wanted to know how much you shouldn't be doing things like these because they are pointless. Real code does not do things like this at all, and there is a reason gcc's optimizations take away all the code (it's pointless and does nothing). Maybe try making a program that does real work and port it to other languages for comparison, if you really wanted to waste your time but do the ``Right Thing'' instead. IHBT, because I replied.

I don't think you understand that the gcc optimization is referring to >>9.
public class Benchmark
{
public static void Main(string[] Args)
{
double a;
for (int x = 0; x < 100000000; x++)
a = 3.14159265 / 1.161803399;
}
}
Results: (compiling just with a plain "csc benchmark.cs". And Windows has no "time" command, so I had to use Powershell)
