Technologies and Methods for Optimizing Web Application Performance

Abstract

The article reviews modern technologies and methods applied to optimize web application performance, emphasizing the direct impact of site speed on user experience, business performance, and competitive positioning. The authors analyze contemporary approaches for enhancing both front-end and back-end performance. Front-end strategies discussed include code splitting, lazy loading, server-side rendering (SSR), image optimization, and minimizing render-blocking resources. Back-end methods encompass various caching strategies, database query optimization, effective API design—particularly comparing GraphQL and REST—and deployment of Content Delivery Networks (CDNs) alongside edge computing solutions. A structured review methodology was applied, synthesizing recent peer-reviewed literature, expert reports, and empirical case studies from industry settings published within the past five years. Quantitative data are provided, illustrating significant performance improvements, including latency reduction, increased throughput, and enhanced user interaction metrics. The authors highlight practical implementation considerations and trade-offs inherent to each technique. Presented findings contribute valuable insights for developers, system architects, and researchers aiming to deliver faster, more reliable, and user-friendly web applications.
