.NET Custom Threadpool with separate instances

Question

What is the most recommended .NET custom threadpool that can have separate instances i.e more than one threadpool per application? I need an unlimited queue size (building a crawler), and need to run a separate threadpool in parallel for each site I am crawling.

Edit : I need to mine these sites for information as fast as possible, using a separate threadpool for each site would give me the ability to control the number of threads working on each site at any given time. (no more than 2-3)

Thanks Roey

Answer 1

I believe Smart Thread Pool can do this. It's ThreadPool class is instantiated so you should be able to create and manage your separate site specific instances as you require.
