I’m building a complex web application using Velo and I’m running into performance issues. What are some common causes of slow load times and how can I optimize my code to improve performance? Are there any Velo-specific tools or techniques I can use to identify and fix performance bottlenecks?

I was wait for very long ago no one can give me perfect answer…

I am waiting please help me.

Best regard,

Hello , Minimize HTTP Requests: Reduce the number of HTTP requests by combining or minifying your CSS and JavaScript files. Use CSS sprites for multiple images and consider lazy-loading techniques for loading images and other assets only when necessary. Code Efficiency: Optimize your code by eliminating unnecessary loops, reducing redundant calculations, and improving algorithm efficiency. Avoid excessive DOM manipulations and optimize your JavaScript code for better performance. Caching: Implement caching mechanisms for static content, such as CSS, JavaScript, and images, to reduce server load and improve load times for returning visitors. Leverage browser caching by setting appropriate cache-control headers for static resources. Database Optimization: Ensure that your database queries are optimized for performance. Use indexes on frequently accessed fields, limit the data retrieved to what is necessary, and optimize query execution plans. Performance Monitoring: Utilize performance monitoring tools and techniques to identify and address bottlenecks. Use browser developer tools to analyze network requests, examine CPU and memory usage, and identify performance hotspots. Velo-specific Optimization: Take advantage of Velo-specific tools like the Velo Performance Profiler, which can help identify performance bottlenecks within your Velo code. It provides insights into code execution time, functions, and database queries, allowing you to optimize your code accordingly. External Services: Optimize your integration with external services by minimizing round trips and utilizing efficient APIs. Implement caching mechanisms for external data where possible to reduce dependency on real-time requests .

  1. Use onReady just one time on your page.
  2. Try to work more on backend.
  3. Try to avoid unneccessary queries.
  4. Do not load to much data at once (do in chunks)
  5. Avoid setTimeOut()
  6. Avoid setInterval()
  7. In some cases go better ASYNC then SYNC.

  10. Optimize images before you add them onto your page (use minimum sized images)

The lower all the data you place onto your site → the better will be the loading performance.
