REST Client: Postman or similar

To make things easier for myself, I leaned on Postman’s code generation capabilities. I first had to copy this Uber API request over from Google Chrome to Postman and replicate it there. There was surely going to be some authentication built in to the request, and instead of monkeying around with manually re-creating that I just used Google Chrome Dev Tool’s “Copy > Copy as cURL” on the request in the Network tab:

Postman – API development and testing tool

You can now test your API using a tool like Postman or curl commands.

For POST, PUT, and DELETE, you'll need a tool like Postman or curl.

The results of the experiment below were as well based on reproducing more than 100 cold and approximately 100.000 warm starts with Lambda function with 1024 MB memory setting and use the ""-XX:+TieredCompilation -XX:TieredStopAtLevel=1" Java compilation option for the duration of 1 hour. The experiments have been performed with the Java Corretto version java:21.v32. For it I used the load test tool hey, but you can use whatever tool you want, like Serverless-artillery or Postman.
