I'm not sure what's your question but maybe this helps:
In short:
The replication daemon is "walking" across your files to check if any files 
need to be replicated to other nodes
(e.g. when a node was broken or a new node is added to the cluster).
Because it is scanning your filesystem it eats up io's. That is why it speeds 
up the system if you turn this off.

The number off objects in a container impacts the sqlite databases. Each 
container is a SQLite database.
The SQLite database will get slower with more objects in them.
I think the recommendations for spinning disks is max a few million for one 
container, when using SSD's for the databases you can go quite a bit higher 
though.

Cheers,
Robert
