What techniques are part of 'Performance Optimization' in Salesforce Commerce Cloud?

Performance optimization in Salesforce Commerce Cloud involves a variety of techniques aimed at enhancing the speed and efficiency of web applications. One of the primary methods utilized is Caching strategies. Caching is essential because it allows frequently accessed data to be stored temporarily, which reduces the need to retrieve the same information repeatedly from the database or external services. This significantly improves response times, reduces server load, and enhances the overall user experience.

By employing caching mechanisms, such as browser caching, server-side caching, and CDN (Content Delivery Network) caching, developers can ensure that users experience faster page loads and that system resources are used more efficiently.

The other options, while related to performance, do not fall under the standard techniques classified specifically as performance optimization within Salesforce Commerce Cloud. Additional servers, hardware upgrades, and bandwidth increases focus on scaling resources rather than optimizing existing performance through more efficient data handling and retrieval processes. Therefore, caching strategies is the most relevant technique for performance optimization in this context.
