Iisapp.vbs:IIS Application Query Script
Reports the process identifier (PID) that provides services for a particular application pool and is currently running the W3pwp.exe process.
Grammar
Iisapp [a/apppoolname |/P AppPoolId]
Parameters
/A AppPoolName
Specifies the name of a particular application pool. (optional)
/P AppPoolId
Specifies the application pool by ID number. (optional)
Comments
If no application pool name or ID is specified, then Iisapp lists all running applications.

The discovery is due to the fact that the W3wp.exe occupies 100% of the CPU, resulting in a huge 80-port footprint and no other operations.
What you see in Task Manager is that w3wp.exe consumes too much resources, so you need to view the PID values of w3wp.exe.
Here's the process of looking for an error site: To find this site, you have to link the problematic process to the site's application pool. First set the Task Manager to view the way to add

In a dynamic server, CPUVP (CPU virtual processor) is a multiple-thread process that runs on the processor unless the following occurs:
1.CPUVP There is no task to do, such as a thread in the ready queue that does not wait for execution.
2. The operating system forces CPUVP to relinquish the CPU to other processes.
In order to optimize throughput consideration
Under IIS6, frequent w3wp.exe memory and CPU usage cannot be released in time, resulting in slow server response.

If the CPU bottleneck suddenly occurs without additional complex conditions, it may be because there is no optimized query, incorrect database configuration, or the reason for database design and insufficient hardware resources.
