Abstract: Optimization of application performance is a critical aspect of software development, especially when dealing with high-throughput operations such as handling HTTP requests. In modern C#, structures Span<T> and Memory<T> provide powerful tools for working with memory more efficiently, reducing heap allocations, and improving overall performance. This paper explores the practical applications of Span<T> and Memory<T> in the context of optimizing HTTP request processing. Real-world examples and approaches that demonstrate how these types can minimize memory fragmentation are presented, avoid unnecessary data copying, and enable high-performance parsing and transformation of HTTP request data. By leveraging these advanced memory structures, developers can significantly enhance the throughput and responsiveness of their applications, particularly in resource-constrained environments or systems handling many concurrent requests. This paper aims to provide developers with actionable insights and strategies for integrating these techniques into their .NET applications for improved performance.
