Multiple threadpool for one process

[Tamir Khason]

Is there "standart" way to use more then one threadpool in one process?
I mean, without custom developed classes, native way??

Thank you

Tamir,

No, there is not. You will have to create another class that handles a
pool of threads on your own.

Hope this helps.

There is only one single CLR threadpool available per process split into two different pools (non I/O style workitems - 25
threads/CPU default,. and one I/O style workitems - 1000 threads/CPU default).
If you need a separate threadpool, you need to implement it yourself.

Mybe (just for case) you know if multiple threadpools will avialiable in C#
v2 (beggining of the next year)?

re: the I/O workitems...1000 threads/cpu? Can you provide a link to any docs
on this? I've not heard of this pool and I'd like to learn more about it.
Thanks

Dave,

I don't know if it's documented somewhere, but the value is reported by ThreadPool.GetMaxThreads. (25 for v1.0 and 1000 for 1.1)
Note that I/O threads are only used for asynchronous I/O operations (BeginRead/Write, etc) and the max. number is process wide not
per processor.

Dave,
Yes the value is excessive, but the value of 25 in .NET v1.0 was just too low for server class applications, I guess MSFT decided to
set such a high value so that resources like memory and CPU would get exhausted before the value would be reached.
Also note that the threadpool threads are all IOCP bound on OSses that support IOCP's.

Willy.

Willy,

Thanks, I get the same reported value. 1000 IO threads seem excessive to me.
That would consume over 1G of virtual address space if each managed thread
was mapped to a unique OS thread. They could use the same thread to handle
multiple async IO operations using IO completion ports. I suspect that value
actually represents something other then actual IO threads. Some data from
MSFT on this would be helpful.

Thanks,
Dave
