Have you tried the settings from the example configuration file
conf/activemq-throughput.xml:

        <persistenceAdapter>
            <kahaDB directory="${activemq.base}/data/kahadb"
enableJournalDiskSyncs="false" indexWriteBatchSize="10000"
indexCacheSize="1000"/>
        </persistenceAdapter>

turning off journal disk syncs should have the biggest impact, however
the tradeoff is some reliability since the default (true) is to do a
blocking fsync on every message.
