Also, API Gateway is incredibly slow. We often have lambdas that run for 20-30 ms, but API Gateway adds another 200 ms extra. We ended up running our own HTTP service in Beanstalk that forwards calls to Lambdas. It's stupid that we can create a better gateway than Amazon using their own services.

Sounds like you might have a config issue. I have Lambda's that take 20ms and API Gateway returns the entire response in ~40-50ms.
