However, this just means the server version of the JVM produces faster, more efficient code than gcc C++ compiler. It doesn't mean one language is faster than another beucase thats impossible. Languages are just a syntax. C++ is seen as some ultimate efficiency lanugage, but people dont' understand that lanugaes are just english like replacements for machine instructions. C++ has pointers, to let you access memory. Does that mean a language without explicit pointers can't produce better optimized code?

And VB.NET is only JIT compiled the FIRST time you run the program. After that you just have the machine code forever. You could try to write a program that executes faster in C++, but you'll find that your not really able to make it run much faster than the machine code VB.NET program.

It's just a bias people have when they see something different. If someting is like

If i > 10
'do stuff
End if

instead of

if(i>10)
{
//do stuff
}

They assume that the complier can't possibly match the machine instructions of a C++ compiler. But that's not true and many languages with a reputation for beling "slow" have outperformed some of the top C++ compilers. They are slow becuase of their design goals. Are they to be interpreted? How many layers of virtual machine does it have? Is it JIT compiled every time or just the first time you run it?

And with that said i'd like to congratulate the Sun for making, maybe the fastest compiler in the world.

And I would like to thank microsoft for making a platform where C++ goes no faster than VB and compiles to the same machine code.
