Examples of MsgUnitWrapper

org.xmlBlaster.engine.MsgUnitWrapper
Wraps a publish() message into an entry for a persistence cache.
There are two options to make this object persistent (measure on a 2GHz Intel Linux laptop with Postgres):

1. QoS and Key are stored as XML ASCII strings, the content as byte[]
This variant takes about 50 microsec to serialize (toXml()) and 380 microsec to create the object again (SAX parse). The size for an empty content is approx. 80 bytes for a medium sized key and QoS.

2. The whole object is java.io.Serialized
This variant takes about 160 microsec to serialize and 750 microsec to deserialize.

So we have chosen the XML variant as it is faster, has no versioning problems and has smaller size
