I am new to Openjdk and mlvm, but I have decades of experience in benchmark
cheating and hackery.
(No, that is not what I am bringing to OpenJDK.)
I went to look at Caliper, and in the tutorial, I saw this:
return dummy; // framework ignores this, but it has served its purpose!
This is no

Two hypotheses come to mind:
* static and virt
Remi, you were right. Disabling tiered compilation sped things up a bit.
But, everything except MethodHandles is slower in JDK 8 than in JDK 7u7.
Especially static and virtual calls (!!)

I ran the same test on a slightly older laptop with both JDK 7u7 and JDK
8-ea-bin-b59-windows-x64-04_oct_2012. Hardware is i5 M430 - 1 CPU x 2 Cores
x 2 HT running Windows 7, 64 bit.
The results are promising in JDK 8 for MethodHandles and strangely,
Reflection and direct calls were slower than JD
Could you rerun the test with a recent JDK 8 build?
