What improves the performance of bundles in Guidewire?

Improving the performance of bundles in Guidewire is significantly enhanced by caching at both local and global levels. Caching works by storing frequently accessed data in a way that can be retrieved quickly, thereby reducing the need to repeatedly fetch the same data from the database or perform complex calculations.

Local caching allows for quick access to data that is specific to the user's session, reducing latency and improving the user experience. Global caching, on the other hand, can store data that is used across multiple sessions or by different users, thus enabling quicker access to shared resources and reducing the load on back-end services. By implementing a robust caching strategy, Guidewire applications can yield substantial performance improvements, especially in scenarios where users are performing similar tasks repeatedly or accessing common data frequently.

While code optimizations, increased server capacity, and regular database maintenance can contribute to performance improvements, they do not address the immediate data retrieval issues that caching effectively resolves. Thus, caching is a critical best practice within Guidewire for optimizing the performance of bundles.
