How to run

Pre-requisites:

• Gatling
• Docker
• docker-compose

Clone both repositories using git clone:

• Java solution: https://github.com/jpcairesf/rinha-2024-q1-java
• Simulation project: https://github.com/zanfranceschi/rinha-de-backend-2024-q1

Enter in the simulation project folder cd rinha-de-backend-2024-q1 and edit the file executar-teste-local.sh (.ps1 for power shell) to properly use your Gatling installation directory.

Inside the simulation project folder, run the containers and the Gatling simulation using docker-compose -f ./../rinha-2024-q1-java/docker-compose.yml up -d && sh executar-teste-local.sh

Constraints

Some constraints were applied to guarantee a fair and more competitive scenario to the challenge.

• 1.5 CPU to distribute between the containers
• 550 MB of memory to distribute between the containers
• Must be able to run in AMD64 architecture

Results

Test results will be generated in the simulation project rinha-de-backend-2024-q1/load-test/user-files/results. Open the index.html file.
