LambdaMetafactory is is a quite frequent bootstrap method for invokedynamic in JDK8. We can do direct method (LambdaMetafactory) invocation as fastpath when proved that bootstrap MethodHandle points to LambdaMetafactory. The modification gives +10% - +35% to lambda linkage performance (depends on amount of lambdas). -- Best regards, Sergey Kuksenko
