Or you can have the browser cache the CORS header for up to 2 hours (cross-browser), for the same performance effect - but it will also work for third party website consumers of your API that you can't just put on your domain. |

Try the API playground[1] on the authors site. Its takes more than 1 secs for me to get a preflight response back.
The preflight request hits fastly and aws apigateway and maybe the application well. There are lot of options to solve the problem at fastly and apigateway as I mention in another comment[2].
I really hope author reads the comments here.
