Hello, For some time now I’m struggling with the time it takes to CompleteMultipartUpload on one of my rgw clusters. I have a customer with ~8M objects in one bucket uploading quite a large files. From 100GB to like 800GB. I’ve noticed when they are uploading ~200GB files that the requests started timeouting on a LB we have infront of the rgw. When I’ve started going through the logs I’ve noticed that the CompleteMultipartUpload request took like 700s to finish. Which seemed ok-ish, but the number seem quite large. However, when they started uploading 750GB files the time to complete the multipart upload ended around 2500s -> more than 40minutes which seems like a way to much. Do you have a similar experience? Is there anything we can do to improve this? How much time does the CompleteMultipartUpload takes on your clusters? The cluster is running on version 17.2.6. Regards, Ondrej
