I prefer to have it checkpoint fairly frequently, which is why I chose
those values.

So this depends specifically on the environment in question.  The more data
retained, the further back a replica can "catch up" to the provider(s) by
using delta-syncrepl.  However, the more data retained, the larger the
database will be.  Whether or not one wants a replica to be able to "catch
up" to a provider if it is several days behind vs reloading it with a fresh
copy of the db from the provider is the real question.

Regardless of the data retention period, I always suggest a frequent purge
interval.  This is because slapd essentially pauses while a purge is
ongoing.  For most environments, a 4 hour purge interval is not noticable.
I've gone to as frequent as every 2 hours for extremely active sites.
