Hm, I vaguely remember that discussion.

The master has the default of 16 threads (ie, I don't specify the 
threads keyword in the slapd.conf file).

As for the cache for syncprov and accesslog db, I am not certain of what 
you are asking for.  I don't have any "cache" type statements for either 
of them in the slapd.conf file and I'm not setting syncprov-sessionlog 
either.
