Micro-benchmarking is tricky to get right.

The results of our measurements were that lambda's are generally as good as or faster than inner classes, depending on the context.

Of relevance is Sergey's Lambda Performance talk @ JVMLS 2013:

IIRC based on those results improvements were made to the lambda meta-fractory code.
