Why microsoft make so hard to change the max Pool Size??
I really need to change it to 50, because I'm using delegates with
BeginInvoke and I saw that they (delegates) use the ThreadPool, but I saw
too that is very complicate to change the ThreadPool size and if I want, I
need to use unmanage resources http://www.csharpfriends.com/Article...?articleID=201
If I use unmanage resources my application will not be portable to others OS
So, somebody know another way or know something that I don't
Thanks a lot

Roll yer own. Simple array of 50 threads or whatever :D
Would be nice to have some greater control over this, in my view its a half
assed effort from them again.

The reason that it is so hard to change the max size is because the
thread pool has been optimized to handle the number of processes in
conjunction with the processes running on the machine.
The idea is that if you have so many threads, you actually start to
shoot yourself in the foot with the time wasted in context switches.
I would recommend using the ThreadPool as is.
Hope this helps.

If you need specific gurantees, i dont recommend using the threadpool.

Thread pool is more than an array of thread objects, though.

I think that with .net we are not only developing simple clients
applications, maybe (in my case) i'm developing a very complete server
application that requiere thousands of simultaneous transactions and my
server will be run alone in a four processor machine.
So, I think that this is a microsoft error, and for this reason a Toub (from
microsoft) designed the ManagedThreadPo ol. With the ManagedThreadPo ol we can
specify the Pool Size
The problem is that .net asynchronous operations, use the framework
ThreadPool and I can't change that. So, in my case the ManagedThreadPo ol is
not useful
Well, anyway thanks for your answer

Willy.
The number of threads in the pool is 25 times the number of CPU's per process, on a Quad CPU that gives 100 worker threads not
counting the IO threadpool (default 1000).
The value of 25 is largely sufficient most of the typical server style applications (managed or non managed), if you feel it's not
and you want a portable solution, you will need to build your own theadpool class, in the mean time you can determine the optimal
value using CorSetMaxThread s.

What kind of guarantee are you looking for? AFAIK when a work item is queued
up and there is no available thread it will create a new one. Do you have
specific timing issues that the threadpool does not satisfy?

Threads and ThreadPool's
If I use a ThreadPool how can I tell when a thead in the threadpool has
exited? I don't want to set a global member variable I would much rather be
able to act on an event
Also (failing this ThreadPool issue) is it possible to create an array of
Worker Threads, can anyone illustrate with code please

Hello,
I have always used a certain design pattern for multithreaded Windows app;
Start new worker thread from UI thread, use events to notify UI threads when
something happens, update UI controls using delegates through .BeginInvoke. I
came across some code samples recently where ThreadPool class is used to
start new threads.
My questions;
1. what's the difference?
2. Any performance benefits?
