An important aspect to consider for any enterprise software project is making sure that it is dimensioned to handle its expected load and also that its performance will be aligned with the current market expectations and usually, with our stakeholders' requirements. 

To address these needs and validate that everything will go smoothly in production and with no performance degradation, typically you will have a load generation tool like JMeter to validate your solutions by putting some load on your systems, and executing a test plan that usually covers your project's most essential scenarios and use cases. An interesting idea to consider while we are at it is that having in mind all the time, sweat, and tears invested in creating these JMeter test plans, why not using them as functional tests as well?! 

With all these in mind and to give you a jump start, I'm sharing here my JMeter 5.3 baseline test plan for Liferay Commerce. It is validated against Liferay DXP 7.1 + Liferay Commerce 2.1.2, but I'm sure that with small adjustments it will be useful on a multitude of different setups. The covered test cases are:

• User authentication
• Commerce account creation
• Add a business address to the account
• Create a Minium site
• Create a new order
• Check-out the order
• Get placed order details

I hope this is information is helpful for you and your projects, and if you need any help with your projects' Performance Tuning process, we at Liferay Global Services are always happy to support you the best way we can!
