I prefer to have it checkpoint fairly frequently, which is why I chose those values.
- What is the recommended value of olcAccessLogPurge?
As per your blog value is olcAccessLogPurge: 01+00:00 00+04:00
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.
