1# Linkerd Load Testing
2
3[slow-cooker](https://github.com/BuoyantIO/slow_cooker) is a Buoyant owned tool used to load test the linkerd solution.
4
5This pallet installs a basic nginx service and a cron job to run slow cooker every hour. Slow cooker will query nginx service 100 qps (5 clients at 10 qps), every 60s, for 60 iterations (1h). This is a long running test.
6
7Adjust the settings in `configuration.json` and update URL endpoints in `urlsconfigmap.yaml`.
