    <p>I was trying to run a performance test for Kryonet RMI, the test results are not convincing. However I think I may not be doing things in the right way. Can I get some feedback on the code below.</p> <h3>SERVER</h3> <pre><code>import com.esotericsoftware.kryo.Kryo; import com.esotericsoftware.kryonet.Connection; import com.esotericsoftware.kryonet.Listener; import com.esotericsoftware.kryonet.Server; import com.esotericsoftware.kryonet.rmi.ObjectSpace; public class Razor { static int port = 2551; static String send = null; // Data Creator, creates data of size s.getBytes().length * 10 static String createMsg(String s){ StringBuilder sb = new StringBuilder(); for (int i = 0 ; i &lt; 10; i++){ sb.append(s); } System.out.println(sb.toString().getBytes().length); return sb.toString(); } // Test Interface public static interface TestInterface { public String getName (String name); } //Class implementing the test interface. static private class TestImpl implements TestInterface { public String getName (String name) { return send; } } public static void main (String[] args) throws Exception { // Creating data of size 160 bytes send = createMsg("FooAndBarAndLazy"); Server server = new Server(); Kryo kryo = server.getKryo(); ObjectSpace.registerClasses(kryo); kryo.register(TestInterface.class); server.start(); server.bind(port); System.out.println("Server started on " + port); TestImpl test = new TestImpl(); final ObjectSpace objectSpace = new ObjectSpace(); objectSpace.register(123, test); server.addListener(new Listener() { public void connected (final Connection connection) { objectSpace.addConnection(connection); } }); } } </code></pre> <h3>CLIENT</h3> <pre><code>import com.esotericsoftware.kryo.Kryo; import com.esotericsoftware.kryonet.Client; import com.esotericsoftware.kryonet.rmi.ObjectSpace; public class TBone { static int port = 2551; // Bytes to MB converter public static float b2mb(long bytes){ float bb = bytes; float ll = 1024 * 1024; return bb/ll; } // Nono Seconds to seconds converter public static float ns2s(long nsecs){ float f = nsecs; float t = 1000000000; return f/t; } public static void main (String[] args) throws Exception { Client client = new Client(); Kryo kryo = client.getKryo(); ObjectSpace.registerClasses(kryo); kryo.register(Razor.TestInterface.class); client.start(); client.connect(50000, "localhost", port); Razor.TestInterface test = ObjectSpace.getRemoteObject(client, 123, Razor.TestInterface.class); String profile = null; int bytes = 0; long stime = System.nanoTime(); for (int i = 0; i &lt; 1000; i++){ profile = test.getName(""); bytes = bytes + profile.getBytes().length; if (i %100 == 0) System.out.println("Done : " + i); } long etime = System.nanoTime(); System.out.println("Total bytes(MB) : " + b2mb(bytes)+" , " + "Total time : " + ns2s((etime-stime))+" seconds"); client.stop(); } } </code></pre> <h3>RESULT</h3> <pre><code>Done : 0 Done : 100 Done : 200 Done : 300 Done : 400 Done : 500 Done : 600 Done : 700 Done : 800 Done : 900 Total bytes(MB) : 0.15258789 , Total time : 26.139627 seconds </code></pre> <p>I would imagine way more performance. Is this a valid test? </p>

    1. COKryonet RMI is a reflection layer built over RMI, so it's going to be slower than raw RMI, particularly on an unrealistic test like this that tests nothing else. I cannot see the point of it myself.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
