Gary Tully resolved AMQ-3646.
-----------------------------

    Resolution: Fixed

fix in http://svn.apache.org/viewvc?rev=1222705&view=rev

A checkpoint won't disk sync when setEnableJournalDiskSyncs=false on kahaDB. \
Checkpoint and cleanup can be disabled altogether with a period of 0. The broker jmx \
view {{gc()}} operation will do a persistence adapter checkpoint/cleanup so it is \
possible to manually force a gc of the store.

                
> Allow KahaDB to run without disk syncs, higher through put without the jms \
>                 persistence guarantee

> Key: AMQ-3646
> URL: https://issues.apache.org/jira/browse/AMQ-3646
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Message Store
> Affects Versions: 5.5.1
> Reporter: Gary Tully
> Assignee: Gary Tully
> Labels: buffer, kahaDB, persistence, sync
> Fix For: 5.6.0
> 
> 
> When using the broker as a buffer for persistent data, large bursts or additions, \
> periodic batch removes, we want to become disk bound. Waiting for disk syncs causes \
> unnecessary pauses. If the JMS durability guarantee is not needed, it should be \
> possible to execute without disk syncs. Syncing only on shutdown.
