When one single program or software uses up most of your CPU resources, your desktop will be unable to run other applications. This may result in slowing down your computer or even freezing it. In many cases, Windows processes or any other 3rd-party application can arouse high CPU usage. If you ever come across to see which application must be using your CPU’s resources, you may notice .Net Framework Optimization Service high CPU utilizing much space. This issue can also appear randomly but also can be due to an update in the “.Net Framework”. It is also known as “mscorsvw.exe,” but commonly, it will be displayed in your Task Manager window under the name “.NET Runtime Optimization Service”.
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.
