Tomcat Users,
The question is this:
How many concurrent accesses can tomcat 4.0.3 support?
Now, I know this may be a function of processing power, but my own tests are
showing it much lower than expected.
Basically did the following:
Created a simple java app that spawns off n threads, each thread making an
access to a file hosted by tomcat. Code snipped shown below:
At n > 17, I start getting
java.net.ConnectException: Connection refused: connect
The number of connetions refused is roughly proportional to the number of
thread over 17.
Is there some configuration I have to change?
I already modified server.xml,
connector acceptCount="100", minProcessors="50", maxProcessors="100" from
the default values, with NO effect.
I also tried using Apache HTTPD and ajp13 (using the same connector settings
as above), with no effect.
I can't believe this low number is truely the # concurrent accesses that
Tomcat can handle, this must be an artifical limit somewhere.
Please advise (and thanks in advance)

SAMPLE CODE:
public class TestClient extends Thread {
public void run() {
URL url = new URL("http://localhost:8080/axis/";);
InputStream in = url.openStream();
URLConnection conn = url.openConnection();
int len = conn.getContentLength();
}
public static void main(String[] args) {
int n = Integer.parseInt(args[0]);
TestClient [] threads = new TestClient[n];
for (int i = 0; i<n ; i++) {
threads[i] = new TestClient();
}
for (int i = 0; i<n ; i++) {
threads[i].start();
}
for ( int i=0; i<n; i++ ) {
threads[i].join();
}
}
}
