How much overhead does Apigee add to a request?

So, I got asked this question earlier today and was surprised that I never memorized an answer.

It’s definitely dependent on your configuration, but for our purposes it looks like it’s about 60 ms. And, it’s probably less than that (see below).

The total time states 267ms, but the response actually sends back to the client around the 220ms mark. Of those 220ms, about 162ms is spent making the round trip to the application server to process the request. Below is a more detailed break down. But, you should be aware that many of the 1ms values listed below are actually < 1ms. The total values are probably lower than the values quoted.
