jbonofre opened a new issue, #1698:
URL: https://github.com/apache/activemq/issues/1698

   The default ActiveMQ configuration is pretty "low" in the binary 
distribution:
   * in `bin/setenv`:
   ** the default `ACTIVEMQ_OPTS_MEMORY` should be updated to a more modern 
configuration, for instance using `-XX:AutoBoxCacheMax=20000 
-XX:+PrintClassHistogram -XX:+UseG1GC -XX:+UseStringDeduplication -Xms512M 
-Xmx2G`
   * the `conf/activemq.xml` should be updated by default:
   ** should we keep the `contantPendingMessageLimitStrategy` in destination 
policies by default ?
   ** should we add `prefetch` configuration in destination policies (for 
visibility) ?
   ** should we add `kahaDB` tuning by default (`checkForCorruptJournalFiles`, 
`indexCacheSize`, `indexWriteBatchSize`, `journalMaxFileLength`, 
`maxAsyncJobs`, ...). The purpose is not to change the default values in the 
code, it's really to "expose" this configuration in the default `activemq.xml` 
to our users.
   ** change the default `systemUsage` ?
