I think I might have been thinking your primitive benchmark but thought it was more complicated 🙂
Basically looking to set up a realistic "typical" REST API...something that supports session token refreshes (for Oauth), login, secured API endpoints, CORS, JWT. Not sure what kind of simple app to do for this yet, but maybe a shopping cart.
I'm surprised Grizzly is so slow too..uses NIO so it should be pretty fast.
