Hi, In our application we are serializing Externalizable objects. In writeExternal(), we basically converting the data into byte[] and writing them into the streams in writeExternal() and readExternal() methods. But when we initially call writeObject() and readObject() methods, they are taking much of the CPU cycles. Can we avoid that overhead if we use JBossSerialization?
