Hello Rob As you said, If any group member exceed 3K then you can experience slow down in server response. But in the big size of operation environment, members( especially the number of hosts) exceeding 3k is not that uncommon. So, I wonder if there is any way you recommend to manage this case such as you split up into several groups internally, or disable some configurations. If there is no reference or guide from IPA about that, I have no option but to face slow-down performance issue ?
