With respect to AWS Lambda specifically, a real consideration is how fast the context loads. In the absence of warming schemes, any performance gains you get using Java for example, might be out weighed by the the cost of loading a much larger (in size) context. In general, the zip for the Lambda implemented in Nodejs is going to be considerably smaller than the zip implmented in Java.

NodeJs, in particular, out performs all language run-times in terms of AWS Lambda cold-start time (<200ms), and is second-best for warm-starts (<11ms) behind Python (<9ms).
