The document discusses using Locust, an open source load testing tool, to test the performance of an Odoo instance. It provides an overview of performance testing and explains why automated testing tools are preferable to manual testing. The document then demonstrates how to install and use Locust to test an Odoo instance running locally and on a VPS server. Sample Locust script and XML-RPC code is shown and explanations are promised but missing. Notes on Locust limitations and alternatives for load testing Odoo are also provided.
