Performance Optimization Techniques


Performance is an integral part of the Application design and plays a vital role in the success of your product/application. This is Part-2 of the performance optimization articles series. Performance optimization considerations for an enterprise-level application are discussed as part of Part-1. Before delving into performance optimization techniques, let us discuss the factors that impact the performance of an application.

The Future of Performance Testing

Alex Podelko

While there are still quite a lot of cases where it is still applicable, it needs to evolve into more sophisticated processes tightly integrated with development and other parts of performance engineering. First of all, integrating into agile development (shift-left / continuous performance testing) and integrating into performance information loop with production (shift-right) to form a holistic performance view.

CSS and Network Performance

CSS Wizardry

Let me address that by combining my two favourite topics: CSS and performance. Broadly speaking, this is why CSS is so key to performance: A browser can’t render a page until it has built the Render Tree; the Render Tree is the combined result of the DOM and the CSSOM; the DOM is HTML plus any blocking JavaScript that needs to act upon it; the CSSOM is all CSS rules applied against the DOM; it’s easy to make JavaScript non-blocking with async and defer.

Performance Budgets, Pragmatically

CSS Wizardry

One of the key tools that performance engineers have at their disposal is the Performance Budget: it helps us—or, more importantly, our clients—ensure that any performance-focused work is monitored and maintained after we’ve gone. Performance budgets should not be things to work toward, they should be things that stop us slipping past a certain point. Example Performance Budgets. Don’t make life difficult by treating performance budgets as aspirations
