When making a large enterprise application, a lot of thought needs to go into the performance. This problem could have been prevented when applications are slow and have timeout errors, for example, and these errors keep happening. This book instructs developers on how to increase the efficiency of their code, detect and eliminate performance bottlenecks, and construct codes that simplify the software execution. \nThis book teaches to improve the performance and reliability of apps so that the business runs smoothly. Readers will learn to employ the correct data types, different pattern matching, application profiling, and performance diagnostics. Various application challenges, including a large object heap, memory cache, system interoperability, and accurate collections, are thoroughly discussed with appropriate solutions. While exploring how to improve application performance, readers will gain hands-on experience with tools like Visual Studio Diagnostic Tools, JetBrains DotMemory, Red Gate ANTS, and dotTrace. \nFurthermore, readers get to practice writing clean codes, use of expert best practices, and design effective UIs responding appropriately to the server and the user.
