Java very limited on max number of threads?

Question

We have a small text box with 512Mb of ram. We wanted to see how many threads we can create in Java in this box. To our surprise, we can\'t create many. Essentially the minimum

Answer 1

Use asynchronous IO (java nio) and you'll don't need 7k threads to support 7k clients, a few threads for handling io (5?) will be enough.
Take a look at Netty ;)

One thread for each client is a really bad design.
