To improve sending/receiving of ObjectMessages I used another serialization
framework (Kryo). I was a bit surprised, because the performance gain was
not as big es expected.
- When using Kryo with ActiveMQ it improved sending/receiving message with
about factor 2,5.
- In my stand alone Java serialization test application (using
ObjectOutputStream/ObjectInputStream vs. Kryo) I got about factor 4.
In both cases I used the same object to (de-)serialize.
Two questions:
[1] Does ActiveMQ already use some kind of optimized Serializer?
When looking in the source code of Active MQ I see something like this:
DataOutputStream dataOut = new DataOutputStream(os);
ObjectOutputStream objOut = new ObjectOutputStream(dataOut);
[2] What's the purpose of slotting a DataOutputStream ahead of a
ObjectOutputStream?
