Comparing the CPU/Memory utilisation of a REST service (Quarkus, Payara Micro, Spring Boot, Python)

Some scripts to measure the CPU and Memory utilisation of JAX-RS appliations. The performance test runs inside a docker container.

The test uses the following demo projects:

• demo-payara contains a simple JAX-RS application packaged as uber-jar with Payara Micro (5.2020.4) application server
• demo-payara-jpa contains an advanced JAX-RS, JSON-B, CDI, JPA, PostgresDB application packaged as uber-jar with Payara Micro (5.2020.4) application server
• demo-quarkus contains a simple Quarkus (1.8.1.Final) application packaged as jar and additionally compiled as native image using the GraalVM Native Image
• demo-quarkus-jpa contains an advanced JAX-RS, JSON-B, CDI, JPA, PostgresDB Quarkus (1.8.1.Final) application packaged as jar and additionally compiled as native image using the GraalVM Native Image
• demo-python contains a simple (REST service) and advanced (REST with DB access) Python application
• demo-spring-boot contains a simple REST service using Spring Boot (2.4.0-M3)
• demo-spring-boot-jpa contains an advanced REST, JSON, JPA, PostgresDB service using Spring Boot (2.4.0-M3)

(1) Prepare and start plot-tests

1. Modify the Dockerfile (look for PROXY) to use a proxy server or not
2. Build the docker image with env_build.sh or env_build.cmd
3. Run the image in a new docker container with env_run.sh or env_run.cmd
4. Build the demo projects inside the docker container with ./scripts/build.sh
5. Run the tests inside the docker container with ./scripts/test-all.sh
6. Plots are generated to directory plots
7. Logs are generated to directory logs

(2) Test scenario

The plot-test consists of the following actions:

• starting the application (simple JAX-RS application)
• wait until the first http request to the JAX-RS endpoint can be served (time to first request)
• sleep 1 second
• start load-test using apache benchmarking tool
  • requests: 5000
  • concurrency: 5
  • url: the JAX-RS endpoint of the application

(3) Plots

All plots are generated on my Notebook inside the running docker container.

Docker Host Machine:
