More info on the setup is required in assessing the case.
Looks like this setup is larger than what I experimented with.
Was this observed only with the refreshAndPersist mode ?

Okay, with refreshAndPersist, what I see is the master's slapd spike when the replica is first started (up to 20% of the CPU), and then drop back down to near 0 once it is done sending everything (about 5 minutes), so that by itself isn't bad. I do wonder what happens in a case like ours, where we shutdown all the servers nightly, then restart -- I imagine having 9 replica's start hammering the master within minutes of each other could have a negative effect.
