I really like the simplicity of Go where the learning curve is very lean but accepting it as a system level programming would be a tough sell. I think it is more for Java/Python developers for building the enterprise softwares rather than using it for hardware/device-drivers/embedded programming, but you never know as Google is very successful selling Android on low powered smart devices.
I did some performance bench for C, C++, D and Go languages using the Fibonacci algorithm.
Results: (see updated results at the end)
For Fibonacci(25), C++ >= Go > C >= Lua-JIT > D > Lua-Terra > Java 1.6
For Fibonacci(50), Java > C > C++ > D-ldc > D-dmd > Go > Lua-Terra > Lua-JIT
Now surprisingly, Java out performed C/C++ for Fibonacci (50) which hurts my ego :) !!

Update:
It seems Clang on MacOS has some issue. I executed these on my Linux Virtual machine with gnu g++ and g++ is outperforming Java. My ego is intact :)

You could try freepascal:
program Project1;
uses sysutils;
function fib(n:int64):int64 ;
begin
if n < 2 then fib:=n
else
fib:=(fib(n-1)+fib(n-2)) ;
end;
begin
writeln('Language Pascal:',(fib(strtoint(ParamStr(1)))));
end.
Why not using Java 8 or even Java 7? Java 6 reached end-of-life already.
I did run with Java 8. Below are results. Java 8 seem to be slower than Java 6 in my results.

Your benchmark is irrelevant.
As is that comment.
Please do "some performance bench".
Please don't just do a 10 line Fib!
At least take tasks/programs from the benchmarks game and do repeated measurements with different workloads.
Better, improve on what the benchmarks game already does.
Cool, fancy writing a proper benchmark now?
My results contradict yours.

I will update the blog. Thanks.
Nice Article!_
Nice article! You did work hard on your blog and I really appreciate your efforts. "Fibonacci" remind me of my Java Practical lab. Thanks for sharing this information and I think that Java is a way more good than other language as far as Performance and Security is concerned.
