What is .Net Runtime Optimization Service?

The Microsoft.NET Framework .NET Runtime Optimization Service (ngen.exe) is a component that seeks to improve the performance of.NET programmes. It works by precompiling.NET assemblies into native machine code, which speeds up the loading and execution of the assemblies during runtime. In the background, the service analyses and optimizes the assemblies, creating optimized copies of the code that are saved in the native image cache. Because the optimized code may be performed directly by the CPU without the requirement for just-in-time (JIT) compilation, this results in quicker startup times and improved overall performance for.NET apps. Hope you understood what is net runtime optimization service.
