When it comes to optimizing the performance of a custom web application, there are several techniques that can be implemented:
1. Optimize database queries:
Efficiently designing and indexing database tables, avoiding unnecessary queries, and caching frequently accessed data can significantly improve performance.
2. Minimize HTTP requests:
Reducing the number of HTTP requests by combining multiple CSS and JavaScript files into a single file, using CSS sprites for images, and utilizing inline CSS and JavaScript can help reduce page load time.
3. Compress and cache content:
Gzip compression can be used to compress resources before serving them to the client. Additionally, implementing client-side caching and server-side caching can reduce the load on the server and improve speed.
4. Use a content delivery network (CDN):
A CDN can help distribute static content to geographically distributed servers, reducing the distance between the user and the server and ultimately improving load times.
5. Implement code minification and bundling:
Minifying and bundling JavaScript and CSS files can reduce the file size and improve loading speed.
6. Optimize image sizes:
Optimizing images by compressing them, using responsive images, and lazy loading can significantly decrease the file size and improve page load time.
7. Implement browser caching:
Setting appropriate caching headers and leveraging browser caching can reduce the number of requests made to the server and improve subsequent page loads.
8. Leverage HTTP/2:
Using HTTP/2 protocol can improve performance by enabling concurrent requests, header compression, and server push.
