It is also important to identify architecture limitations that might change a non-functional requirement.
    - Development phase
      During the development phase, it is important to measure the response time of business critical steps in the development environment.
    - Testing phase
      During the testing phase, it is important to start with simple, common test cases and gradually go to more complex scenarios and environment configurations. Other priorities include measuring the performance of the application as load scales up to projected peak and identifying and resolving the root causes of resource constraints and application bottlenecks.
    - Maintenance phase
      Post-launch, during the maintenance phase, instrument and monitor performance indicators in the production environment to enable the team to proactively identify and address potential issues before users are affected. Priorities also include fostering communication between marketing, performance, and operation teams to be better prepared for promotional events. And using the data that is captured from production to optimize planning for future marketing and promotional activities.
    - JDBC_MONITOR_ENABLED parameter
      JDBC Monitor (Java Database Connectivity) is a debugging tool that allows you to examine SQLs that are executed in any application for performance and troubleshooting purposes. This document provides the installation steps for JDBC Monitor.
    - Tuning
      A Commerce+ deployment consists of multiple components working together to deliver the e-commerce experience. By default, each component is set up for baseline performance, but individual optimizations can enhance overall efficiency. The following topics outline how to fine-tune these components for improved performance.
      - Commerce+ performance tuning
        Commerce+ by itself does not have too many performance tuning knobs. Consider Commerce+ to be a Java EE application that consists of business logic and relies on Open Liberty Server to provide the core function to make Commerce+ perform well.
      - Tuning best practices
        Use these tips and best practices to help you successfully work with Workspaces and Commerce Search, deploy Commerce+, and develop reusable and easily maintainable JSP pages within the Commerce+ store development framework.
