Performance matters for user experience. Here are proven techniques for keeping your Oorian applications fast.
Minimize DOM Updates
Batch UI changes when possible rather than updating elements one at a time.
Use Server-Side Pagination
Never load thousands of rows into a grid. Use server-side pagination.
Lazy Load Content
Load tab content only when the tab is activated. Load modal content only when opened.
Choose Appropriate Communication
Use AJAX for simple interactions. Reserve WebSocket for real-time needs.
Profile Before Optimizing
Use your IDE's profiler to find actual bottlenecks rather than guessing.
Conclusion
Most performance issues stem from loading too much data or updating the UI too frequently. Address these first.
