This section studies the priority of the process and the setting of the nice value. In the case of high CPU load, high priority processes take precedence. RHEL7 priority = Priority coefficient +nice value to determine. The precedence factor can be seen as a static value for a kernel, so we can change the priority by resizing Nice. Nice's values range from 20 to 19, and the higher the number, the lower the priority. Nice defaults to 0First change the C

The HttpApplication object was created by ASP., which is an important object in ASP. NET to process the request. To facilitate extensibility, HttpApplication is handled in a way that handles pipelines, dividing the steps of processing into multiple steps, each of which is exposed to the programmer in the form of events, which are triggered sequentially in a fixed order of processing. Programmers can define a request extension process by writing an event-handling method.For HttpApplication, to AS
