I have <10 users and <10 servers....I cant see any tuning is necessary as 
yet....

However I did up the cache and that made no difference....

original

[root@vuwunicoipam001 ~]# ls -lh 
/var/lib/dirsrv/slapd-ODS-VUW-AC-NZ/db/userRoot/id2entry.db4 -rw-------. 1 
dirsrv dirsrv 6.3M May 8 11:34 
/var/lib/dirsrv/slapd-ODS-VUW-AC-NZ/db/userRoot/id2entry.db4 
[root@vuwunicoipam001 ~]#

=======
grep cache /etc/dirsrv/slapd-ODS-VUW-AC-NZ/dse.ldif nsslapd-dbcachesize: 
10000000 nsslapd-import-cache-autosize: -1 nsslapd-import-cachesize: 20000000 
nsslapd-cachesize: -1 nsslapd-cachememsize: 10485760 nsslapd-dncachememsize: 
10485760
=======

modded
=======
So to sum up, please change nsslapd-cachememsize parameter in 
/etc/dirsrv/slapd-<instance>/dse.ldif from; nsslapd-cachememsize: 10485760 to 
nsslapd-cachememsize: 18900000
=======

Presently my cache size has shrunk from 6.3meg to 616k....

[root@vuwunicoipam001 ~]# ls -lh 
/var/lib/dirsrv/slapd-ODS-VUW-AC-NZ/db/userRoot/id2entry.db4 -rw-------. 1 
dirsrv dirsrv 616K Jun 6 09:42 
/var/lib/dirsrv/slapd-ODS-VUW-AC-NZ/db/userRoot/id2entry.db4 
[root@vuwunicoipam001 ~]#

Though on the replica its a different size (but then I have a split brain 
issue.... 

[root@vuwunicoipam002 ~]# ls -lh 
/var/lib/dirsrv/slapd-ODS-VUW-AC-NZ/db/userRoot/id2entry.db4 
-rw-------. 1 dirsrv dirsrv 752K Jun  6 09:51 
/var/lib/dirsrv/slapd-ODS-VUW-AC-NZ/db/userRoot/id2entry.db4
[root@vuwunicoipam002 ~]#

Did you do the "max entry cache size" tuning? If you did, what did you set it 
to?

Did you do any other tuning from the 389-ds tuning guide?
