Spring Boot vs Micronaut performance tests

Few words about projects:

• Micronaut - Micronaut with dependencies: Web, JPA, Lombok, Validations
• Spring - Spring Boot with dependencies: Web, JPA, Lombok, Validations
• Micronaut_Mongo - Micronaut with dependencies: Web, Mongo (standard driver, not reactive), Lombok, Validations
• Spring_Mongo - Spring Boot with dependencies: Web, Mongo, Lombok, Validations

Project with Customer+Product+Order func

Prerequisites: MongoDB

A few simple endpoints have been created in the projects so that the tests are done on something more than "hello-world example". In each app context are 180-220 beans.

Build using:

mvn clean install

Run using:

java -jar path-to-jar

Project with Customer+Product+Order func & 1000 beans auto-generated

In each app context are circa 1200 beans. If you want check exactly number, change property beans.counter (in application.properties for Spring and application.yml for Micronaut) to true.

Run performance tests

Prerequisites: Scala

Go to gatling-performance-tests and run all simulations:

mvn gatling:test

Only for Spring Boot:

mvn gatling:test -Dgatling.simulationClass=simulations.SpringSimulation

Only for Micronaut:

mvn gatling:test -Dgatling.simulationClass=simulations.MicronautSimulation

Only for Mongo Spring Boot:

mvn gatling:test -Dgatling.simulationClass=simulations.MongoSpringSimulation

Only for Mongo Micronaut:

mvn gatling:test -Dgatling.simulationClass=simulations.MongoMicronautSimulation

Beans generator

We use Lusk to generate some example beans for apps.

Generate 1000 beans in generated package:

lusk -c1000 -fmicronaut -p "pl.altkomsoftware.micronaut.perftest.generated" [path-to-repo]\micronaut-1-1-0

lusk -c1000 -fspring -p "pl.altkomsoftware.spring.perftest.generated" [path-to-repo]\spring-boot-2-1-4

TODO

• Create WebFlux Spring version
