It would be better know what exactly do want to test? "Testing parallel 
API" is too general, let's start from small pieces.

I'd like to see your results, how did you do measurement and etc. Your 
conclusion "not so good" don't bring us any information.
Which parts of lambda life cycle did you measure?

What does it mean "fast enough" if we are talking about invokedynamic?
Again, which parts of lambda life cycle do you want evaluate in case of 
concurrent program? Don't forget, invokedynamic is used only for lambda 
linkage, indy isn't used neither by lambda capturing nor by lambda 
invocation.
