Before we dive into the details of fixing .NET Runtime Optimization Service High CPU, it is imperative to what exactly is High CPU usage and CPU time.
According to Wikipedia, CPU time is the amount of time for which a Central Processing Unit (CPU) was used for processing instructions of a computer program or operating system, as opposed to elapsed time.
The measurement of CPU time is termed in clock ticks or seconds. Another name used for CPU time is Process time. The main reason why we measure CPU time is to calculate the percentage of CPU’s capacity also known as CPU usage.
Sometimes a third-party application can stimulate high CPU usage. If your CPU usage is high, your system will slow down and you will see .NET Runtime Optimization Service in the Task Manager. .NET Runtime Optimisation Service will also use a load of resources of your CPU.
Now let us discuss what causes high CPU usage.
