Minimization and Concatenation
- Remove whitespaces and unwanted characters to reduce the size of assets on the front end (HTML CSS JavaScript). Combine multiple files in a single request. This will reduce the round-trip time.
Content Rendering Optimization
- Optimize the rendering of pages so that critical content is loaded first (e.g., content above the fold). The "lazy-loading" method improves the perceived performance.
Browser Caching
- Use browser caching by instructing browsers to store certain assets locally. It is easier to visit a site again without downloading all the resources.
Content Delivery Optimization
- Content Delivery Networks and global server networks can deliver content to servers closer to the users. It reduces the latency for all users and speeds up loading times.
Mobile Optimization
- Optimize your software for mobile devices. Improve mobile performance by using responsive design, lazily loading images and JavaScript.
Regular Performance Testing
- Perform performance tests regularly, particularly after major updates or modifications. Recognize and correct performance regressions as soon as possible.
Capacity Planning
- Monitor resource usage continuously and upgrade capacity as necessary. By scaling infrastructure in advance, performance bottlenecks can be avoided.
