syncrepl (re)sends the entire entry, so it's a lot more intense than your 
typical MOD. I seem to be the only person willing to live with this, but 
it's quite common to use "delta-syncrepl" instead, which only sends the 
changed attributes. There should be ample documentation out there; read up 
and come back if you have questions. (I'll probably change off of 
traditional syncrepl when I move production to 2.4.)

Apart from that, make sure that your slaves are sanely configured in terms 
of cache, DB_CONFIG, etc. It sounds like you've got your master tuned to 
your liking, so you could follow lessons learned there.
