Long time of initialize() GoldSrc server.

[ghost]

Someone knows why the time initialize() server is not directly proportional to the increase of the number of respondents servers? 1 server: 0.100690964 s 2 servers: 4.701786192 s 3 servers: 4.859124065 s 4 servers: 9.422729783 s 5 servers: 14.101701261 s 10 servers: 15.83547205 - 23 s 20 servers: 15.836554095 - 71.335466586 s

Maybe i am made something wrong, or maybe need use multithreading?

I am use a code:

try {
    MasterServer master = new MasterServer("141.101.245.171:27010");
    servers = master.getServers();
} catch (SteamCondenserException e) {
    e.printStackTrace();
    System.out.println("SteamCondenserException e happened");
} catch (TimeoutException e) {
    e.printStackTrace();
    System.out.println("TimeoutException e happened");
}

long start = System.nanoTime();
for (int i = 0; i <= 10 - 1; i++) { // for initialize 10 servers
    try {
        System.out.println("Start initialize...");
        GoldSrcServer temp_server = new GoldSrcServer(servers.get(i).getAddress(), servers.get(i).getPort());
        temp_server.initialize();
    } catch (SteamCondenserException e) {
        //e.printStackTrace();
        System.out.println("SteamCondenserException if initializing the socket fails");
    } catch (TimeoutException e) {
        //e.printStackTrace();
        System.out.println("TimeoutException if too many timeouts occur while querying the server");
    }
}
long end = System.nanoTime();
long traceTime = end - start;
System.out.println(traceTime / 1000000000.0);
}

initialize() makes several requests to a server. Depending on the response time of an individual server this may vary from server to server. Additionally a server might respond faster or slower from time to time.

Generally, you might leverage better results when using multi-threading, but the times for an individual server might still vary a lot.

Ok, i am using threads for this (pool of 50 threads). But this not so fast as in standard serverbrowser by Steam or in game.

        ExecutorService executor = Executors.newFixedThreadPool(50);
        for (int i = 0; i < servers.size() - 1; i++) {
            Runnable worker = new GetServersInfo(servers.get(i).getAddress().toString().replace("/", ""), servers.get(i).getPort(), "" + i);
            executor.execute(worker);
        }
        executor.shutdown();
        //while (!executor.isTerminated()) {        }
        System.out.println("Finished all threads");

    public class GetServersInfo implements Runnable {

        private String address;
        private int port;
        private String command;

        public GetServersInfo(final String address_arg, int port_arg, String s) {
            this.address = address_arg;
            this.port = port_arg;
            this.command = s;
        }

        @Override
        public void run() {
            System.out.println(Thread.currentThread().getName() + " Start. Command = " + command);
            try {
                GoldSrcServer temp_server = new GoldSrcServer(address, port);
                temp_server.initialize();
            } catch (SteamCondenserException e) {
                //e.printStackTrace();
                System.out.println("SteamCondenserException if initializing the socket fails");
            } catch (TimeoutException e) {
                //e.printStackTrace();
                System.out.println("TimeoutException if too many timeouts occur while querying the server");
            }
            System.out.println(Thread.currentThread().getName() + " End.");
        }

        @Override
        public String toString() {
            return this.command;
        }
    }

Like said before initialize() makes several requests. At least the request for a challenge number is not required if you just want to list the servers. So you might be better off with just using the following:

temp_server.updatePing();
temp_server.updateServerInfo();
