Doc Text:	.A performance decrease when listing buckets with large object counts due to a regression was resolved RADOS Gateway introduced a peformance regression as a byproduct of changes in {product} 3.2z2, which added support for multicharacter delimiters. This could cause S3 clients to time out. The regression has been fixed, restoring the original performance when listing buckets with large object counts. S3 clients no longer time out due to this issue.	Story Points:	---
