1. IIS thread pool W3 thread pool (W3TP)

When HTTP. sys in kernel mode receives a request from a user, the request is placed in the queue. How does the w3wp process in user mode remove requests from the kernel-mode queue? The I/O completion port (IOCP,I/O completion port) shines. There are programs in w3wp that specialize in this W3TP+W3DT (DT may refer to data transfer), which can be captured by the Process Explorer.

2.. NET thread pool

When the request is W3TP through W3DT from the HTTP. SYS queue, the next work is forwarded to ASP. NET, and another thread pool is in the ——. of the Nets thread pool.
