SAP Fiori Slowness and available solutions as way forward.

We often get complaints from end user's about slowness while accessing SAP Fiori. This topic needs highest attention from SAP and I am aware they are working on it since long. Here is my take on this on the problem and possible solutions available as on today.

Main reasons for SAP Fiori slowness:

jQuery Reliance: The UI5 framework at the core of Fiori uses jQuery, which can contribute to slowness due to its direct DOM manipulation and complexity.

Large applications: Fiori applications can sometimes be feature-rich, leading to heavier code and slower loading times.

Network issues: Connectivity or network problems adds in case it's SAP on Rise or SAP on Cloud kind of setup if there are no Site to Site VPN or Express route or similar network setup in place. Plus server-side bottlenecks also affect Fiori's performance if not sized well.

Customization: Overly customized Fiori interfaces might introduce bloat and performance issues.

Ways to make Fiori faster and more appealing:

SAP's efforts: SAP is actively working on improving Fiori performance by migrating parts of UI5 to a newer, faster framework called OpenUI5. They're also optimizing existing components and reducing code size. Below are the links for more details.

Front-end optimizations: Techniques like code minification, caching, and lazy loading can improve Fiori's speed.

UI/UX enhancements: Modern front-end libraries like React, Vue.js, or Angular offer smoother performance and more visually appealing design options. However, migrating Fiori entirely to these frameworks might require significant effort.

Focus on essential features: Simplifying Fiori interfaces by removing unnecessary functionality can lead to a faster and less cluttered experience.

Next steps:

• Share your experience as end user or Functional Consultant: Instead of simply stating "It's very slow," describe specific situations to the SAP Admin or Developer where you encountered slowness. This will provide valuable context for developers or admins to assess the issue.
• Focus on solutions: Offer your suggestions for improvement, such as prioritizing specific features or exploring front-end optimization techniques.
• Consider the trade-offs: Remember that performance improvements often come at the cost of complexity or development or architecture change effort. Be open to finding the right balance for your needs.

By understanding the technical reasons behind slowness and proposing feasible solutions, you can contribute to a more productive discussion about improving SAP Fiori.
