Hm.  What is the typical delta in the mod times of the log files?  It
sounds like you are in a regime where checkpoints are always triggered
by checkpoint_segments and never by checkpoint_timeout, in which case
increasing the former might be a good idea.  Or decrease the latter,
but that could put a drag on performance.
