Hi,

Thanks for getting back to me!
Yeah - Im the same guy from the sun forums :o)

Here's an example type I came up with to test with - which - for me - is serialized much faster with standard serialization than with jboss serialization:

class DomainObject implements Serializable {

 private static final int CHILD_COUNT = 100;

 private DomainObject[] children;
 private long aLong = 45;
 private String aString = "test";
 private int anInt = 4;

 DomainObject() {
 this (true);
 }

 private DomainObject(boolean hasChildren) {
 if (hasChildren) {
 children = new DomainObject[CHILD_COUNT];
 for (int i=0; i<CHILD_COUNT; ++i) {
 children = new DomainObject(false);
 }
 }
 }
 }

Maybe you are doing the test for a one time only, and probably considering meta-data discovery for both Java and JBossSerialization.

You have to start measuring it after you've get steady state. (after few messages).


If you still think JBossSerialization is slower for your class, I would like to take a look on what behavior you are dealing with.

Hi,

I should probably provide you with some more context.
The serialized objects are being sent over JMS (not JBoss, Im afraid ;o)
The provider really doesn't do ObjectMessages very well (forces serialization to be synchronized - even though its a CPU only task - and I run on a 4 CPU machine....).
So, what I have to do is serialize myself and then use the resultant bytes to create a byte array (so I can stuff it in a simple JMS MapMessage or whatever).
Each message is "one-shot" and straight in to memory - there is no underlying IO - this is completely CPU bound stuff.

So, what I do is:

ByteArrayOutputStream baos = new ByteArrayOutputStream(someAppropriateInitialSize);
ObjectOutputStream out = new ObjectOutputStream(baos) / JBossOutputStream(baos);
out.write(myObject);
out.close();
byte[] wireFormat = baos.toByteArray();

There is some "problem" in the way I'm doing reflection for arrays.


I'll find the bottleneck, fix and get back to you through this forum.



Thanks, this is being very helpful.

If you would like to be a contributor on JBossSerialization, I would be glad to give you an overal on the design. It's not that complicated and since you know reflection.... ;-)


If you are interested, let me know.

Ooops,
