Performance Comparison of Jax-RS implementations and embedded containers
Gajotres have written an article: Top 8 Java RESTful Micro Frameworks. He listed 8 best light weight Java RESTful framework. Personally, I perfer jax-rs implementations and micro frameworks for deploying applications as micro services and those micro services can be deployed in docker containers.
So I have test five Jax-RS implementations plus embedded containers despite business logics. The RESTful service is very simple and it only returns a "hello world" string. Remember, tests don't contain any business logics even JSON libraries. There are other articles to dicuss serialization framework. For example, my test
I have added more RESTful framework besides Jax-RS implementation, which contains:
You can check the test result and the performancre chart.
It is a multiple-module maven project. You can run "mvn package" in parent directory to packge each module. It generates a fat-jar in target directories of modules for each module. It is easy.

the test cmd is like:
wrk -t16 -c1000 -d30s http://127.0.0.1:8080/rest/hello.
I use 16 threads and 100/200/500/1000 connnections to test each case.

It looks Resteasy is better than jersey whatever jersey uses grizzly2 or jetty container.
It is predictable that performance of dropwizard is same to jersey+jetty.
Resteasy is excellent in undertow and netty.
To my surprise is resteasy+undertow is a little better than resteasy+netty. Maybe they are all developed by JBoss and they have done some optimization.
I do not recommend you use spring boot in large projects because its performance and style.
Of course native netty is number one but my test has not contains a http router so maybe you can't say it is RESTful framework. But I like its perforamnce.
Performance of RESTEasy+netty4 is lower than what i expect. but RESTEasy+netty3 is very good.
One interesting framework is Vert.x. I like its functional programming style but its performance is not so good.
I have not monitored the CPU usage and memory usage. You can try it.
