Servlet Concurrency problem
Hi, we are trying to develop a servlet, but ive encountered some problems
with the concurrency.
The problem is that only 2 HttpRequest is dispatched at the same time.
the doPost body is the following:
<code>
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
{
System.out.println("START");
try { Thread.sleep(5000); } catch (InterruptedException e)
{e.printStackTrace();}
response.getWriter().write("Hello World!!");
System.out.println("END");
}
</code>
The request is waiting for 5 seconds, and later, return "Hello World!"
In our tests, when i launch 4 request, only 2 is running at the same time,
and when the first finiched, the third request is proccesed..
¿How can I solv this problem?
PD: Sorry, im Spanish, and my English is not well.

Or use wget, ab, jmeter, etc.

I'm guessing these requests are from the same browser. The browser
limits the number of connections it makes to the server to 2. If you
really need more, google for hacks to the browser to allow more.
