Thanks for the reply,
gnutls is a pain but we've been able to make it work and the boss hates it when we use source so I'm kind of stuck with it as it is unless I can make a better case than ssl.
You need to use a current release, regardless of whether or not you avoid using GnuTLS (although from a security standpoint, it should be avoided). You really should read over https://www.openldap.org/software/release/changes.html as well.
There's no point in configuring MMR or answering any questions about it until you get to a current build, given all the MMR related fixes since 2.4.28.
One final note -- If you switch to using back-mdb instead of the back-hdb/bdb databases, I wouldn't particularly worry about write load either.
http://wiki.zimbra.com/wiki/OpenLDAP_MDB_vs_HDB_performance. back-mdb is massively faster for writes than back-hdb/bdb ever were. It is also massively faster for reads in the concurrent read tests (I'm working on getting those posted, the wiki is under constant updating atm. ;) ).
Finally, if you are going to roll out MMR, I strongly advise delta-syncrepl MMR for the primary database. I personally do not replicate cn=config, so can't really speak to configuring it for replication.
