What are asynchronous callbacks ?
Answer Posted / hrdiya
Page processing begins on a thread-pool thread, but that
thread is returned to the thread pool once an asynchronous
I/O operation begins in response to a signal from ASP.NET.
When the operation completes, ASP.NET grabs another thread
from the thread pool and finishes processing the request.
Scalability increases because thread-pool threads are used
more efficiently. Threads that would otherwise be stuck
waiting for I/O to complete can now be used to service
other requests. The direct beneficiaries are requests that
don't perform lengthy I/O operations and can therefore get
in and out of the pipeline quickly. Long waits to get into
the pipeline have a disproportionately negative impact on
the performance of such requests.
