Re: low persistent messaging performance using kahadb

Hi Rob, 
 I had the same issue, and found out that KahaDB performance is heavily
dependent on the maximum sync rate of the filesystem. KahaPersistenceAdapter
is generally faster as described. My questions are: 
-is KahaPersistenceAdapter as reliable as KahaDB?
-does it guarantee persistence of queues? I do not need Topic durable
subscriptions, only guaranteed delivery for queues
-enableJournalDiskSyncs="false" speeds up KahaDB a lot, but, does it
guarantee persistence of messages in all cases?

Thanks, 
Carlo
