Thread Pool's decreasing application performance

Question

Hi,
In my application, I need to make 10,000 threads for network calls at one instant and release the threads after downloading content.
Content downloading of individual thread consumes less than 1min.
When I try this using Timer Task and normal Threads, it works perfectly.
But after introducing ThreadPool (initial :20,000 ; maximum: 50,000) , the response has degraded.
Is there any limitations or known issues similar to this for thread pool's.
Thanks!

You'll hit problems at that level long before the number of threads becomes a problem.

But after introducing ThreadPool (initial :20,000 ; maximum: 50,000) , the response has degraded.You want to have 10000 Threads and declare a pool with 20000 initial threads? Why?
