HttpURLConnection最大吞吐量

Question

I was using the HttpURLConnection to make multiple short requests in the sequence to a server HttpServer . What is the maximum throughput that I can expect? I am not able to get it upwards of 25 records/second.

I need to get it upwards of atleast 5000 records/sec. Is this a right approach to use HttpURLConnection ?

Below is my client code:

public class TestGatewayUser {

    public static void main( String[] args ) throws IOException {

        byte[] bytes = TestGatewayUser.getDataAsBytes();
        Date d1 = new Date();
        for ( int i = 0; i < 10000; ++i ) {

            URL url = new URL( "http://IP:PORT/fetchInfo" );
            HttpURLConnection conn = ( HttpURLConnection ) url.openConnection();
            conn.setRequestMethod( "POST" );
            conn.setRequestProperty( "Content-Type", "application/x-www-form-urlencoded" );
            byte[] bytes = TestGatewayUser.getDataAsBytes();

            conn.setRequestProperty( "Content-Length", Integer.toString( bytes.length ) );
            conn.setUseCaches( false );
            conn.setDoInput( true );
            conn.setDoOutput( true );
            conn.connect();
            OutputStream out = conn.getOutputStream();
            out.write( bytes );
            out.flush();
            out.close();
            int responseCode = conn.getResponseCode();
            InputStream stream = conn.getInputStream();
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            byte[] b = new byte[1];
            while ( stream.read( b ) != -1 ) {
                bos.write( b );
            }
            byte[] byteArray = bos.toByteArray();
            stream.close();
            if ( i % 200 == 0 ) {
                System.out.println( 200.0 / ( new Date().getTime() - d1.getTime() ) * 1000 );
            }

           conn.disconnect();//**Should I use this or not? Java Doc says optional.**
        }
        Date d2 = new Date();
        System.out.println( d2.getTime() - d1.getTime() );
    }

    private static byte[] getDataAsBytes() throws IOException {
        StringBuffer buf = new StringBuffer();
        buf.append( "1367249:2,4,5,31,32,35,59,68,77,389,532,558,353,30002,371" );
        return buf.toString().getBytes();
    }
}

Thanks for helping me.

You're not going to get 5000 connections opened, data sent, and all 5000 connections closed in a second in this method, using one machine.

If you were able to do it on the client, you'd likely kill the server machine; most web apps that go over 100 q/s are serving mostly cached data.
