c# - What is the maximum number of threads available in Asp.net ThreadPool

Question

Just out of curiosity , What is the maximum number of threads available for handling request in asp.net.

And does asp.net releases them for any I/O or database operations so that maximum number of requests can be handled?

Answer 1

It is controlled via machine.config.

configuration > system.web > processModel

<processModel 
   maxWorkerThreads="num"
   maxIoThreads="num"
   minWorkerThreads="num"
   minIoThreads="num"
   ...
   />

It is set on a per CPU basis. Default for single CPU is 20/20.
