Hi Edward,
please list, correct me if I'm wrong
I think may be the amount of "log_file_sync" could help you too. But I
think you should substract
DBWR waits on this event.
I also think that 'user commits' statistics is independent of group
commits, this statistic is updated whenever a user issues a commit and group
commits is just a way LGWR can write entries from log buffer to redo logs.
HTH
greetings
DC
