Re: Thread question

I don't have an exact answer to your question, but remember that each 
thread has to contain a stack of its own, and therefore takes up 
memory.  The 'java.nio' (new i/o) package in recent versions of Java 
was designed for exactly this case that you're mentioning, where you 
have a lot of connections with little traffic and it's definitely the 
way to go, rather than trying to manage 10,000 threads.
