<div dir="ltr">Allow me to rephrase. I've read somewhere (can't remember where) that it would be faster to upload files if they would be uploaded to separate containeres. This was suggested for a standard swift installation with a certain replication factor. Since I'll be uploading the files with the replicators turned off, does it really matter if I insert a group of them in separate containeres?</div>

I'm not sure what's your question but maybe this helps:<br>
In short:<br>
The replication daemon is "walking" across your files to check if any files need to be replicated to other nodes
<br>
(e.g. when a node was broken or a new node is added to the cluster).<br>
Because it is scanning your filesystem it eats up io's. That is why it speeds up the system if you turn this off.<br>
<br>
The number off objects in a container impacts the sqlite databases. Each container is a SQLite database.<br>
The SQLite database will get slower with more objects in them. <br>
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.<br>
<br>
Cheers,<br>
Robert<br>
