[jboss-jira] [JBoss JIRA] Commented: (JBCACHE-937) Benchmark VersionAwareMarshaller

    [ http://jira.jboss.com/jira/browse/JBCACHE-937?page=comments#action_12357472 ] 

Manik Surtani commented on JBCACHE-937:
---------------------------------------

This shows the VAM to be (much) faster than just serializing the method call, although the VAM + Java Serialization is quicker than the VAM + JBoss Serialization.  I'm waiting on some comments from Clebert about this, although here is his initial response:

"in recent Java5 (they have ported the fix to java4 as well) they have
fixed the synchronized caching what was one of the advantages of jbser.
(don't know if pressured by jboss-serialization or not)."

We need to decide whether it still makes sense to ship with JBoss Serialization, or to simply recommend using a JVM with synchronized caching.

> Benchmark VersionAwareMarshaller to make it more performant. There's already a
> unit test to use it as base: VersionAwareMarshallerPerfTest.
> It should probably make comparison failures based on results from different
> marshalling methods, i.e, if difference bigger than x, fail. Also add marshalling different
> types of objects.
> Potential performance improvements:
> - Using similar techniques as used in ExposedByteArrayOutputStream (JGroups) for VAM? 
> Needs profiling to determine effect.
