hi,
Here's a new test. Even here the jboss socket comm (with/ without jboss
serialization) does badly.The machines are the same linux boxes and no other
process is runnin on it.
First we ran the test for 1000 times(say this as a batch) and 15 such batches.
Took the average of last 12 of them(considering jvm warmups etc). We did this
for Java RMI with raw_socket (or javaRMI with java serialization) Then we did
the same with Jboss RMI over socket (socket transport with jboss
serialization). We did this as the same process and as a different processes.
In all the cases socket transport with java serialization took abt 35% more
time than java RMI with java serialization.
Now considering jboss RMI with jboss serialization it takes more than 10 times
w.r.t. java RMI with java serialization. I am not sure where i am doing wrong.
below is the code
public class Person implements Serializable {
| int id;
| private Vector<Person> personVector = null;
|
| //HERE WE POPULATE A TREE WITH A GIVEN DEPTH AND BREADTH.
| public Person populateDepth(Person person, int currentDepth, int
breadth, int finalDepth) {
| if (currentDepth >= finalDepth) {
| return person;
| } else {
| person.personVector = new Vector<Person>(breadth);
| this.id = this.personID++;
| for (int i = 0; i < breadth; i++) {
| Person p = new Person();
| person.personVector.add(p);
| populateDepth(p, currentDepth + 1, breadth,
finalDepth);
| }
| }
| return person;
| }
|
| //DOES THE JAVA SERIALIZATION
| public byte[] getJavaBytes() throws Exception {
| ByteArrayOutputStream st = new ByteArrayOutputStream(64 * 1024);
| ObjectOutputStream os = new ObjectOutputStream(st);
| os.writeObject(this);
| byte[] s = st.toByteArray();
| return s;
| }
|
| //DOES JBOSS SERIALIZATION.
| public byte[] getJbossBytes() throws Exception {
| ByteArrayOutputStream st = new ByteArrayOutputStream(64 * 1024);
| ObjectOutputStream os = new JBossObjectOutputStream(st);
| os.writeObject(this);
| byte[] s = st.toByteArray();
| return s;
| }
|
| //STRESS CODE
| public static long stress(IRemote playerInterface, Person player, int hits)
throws Exception {
| long startingTime;
| long endTime;
| startingTime = System.currentTimeMillis();
| for (int i = 0; i < hits; i++) {
| Person result = playerInterface.execute(player);
| }
| endTime = System.currentTimeMillis();
| return endTime - startingTime;
| }
|
| }
|
|
Also we see Jboss serialization to produce 40% more bytes than java
serialization for the above prog.
Cleint prog is as follows
| uri= "socket://10.1.131.96:8092?serializationtype=jboss";
| int depth=15;
| int breadth =2;
| remote = (IRemote) TransporterClient.createTransporterClient(uri,
IRemote.class);
| Person p = new Person();
| p = p.populateDepth(p, 0, breadth, depth);
| return Person.stress(remote, p, hits);
