Description

The current default setting for `rgw_multipart_min_part_size` is 5MiB/5242880 (which is same as AWS minimum value). Consequently, many clients default to sending large files with 5MiB chunks.

Howerver, the default value for `rgw_obj_stripe_size` stands at 4MiB/4194304. As a result, in a multipart upload utilizing 5MB chunks, each chunk would divide into two rados objects, a 4MiB one and 1MiB one.

Adjusting `rgw_obj_stripe_size` to 5MiB resolves this issue by eliminating the creation of an additional rados object. Are there any other reasons to keep the current value of 4MiB for `rgw_obj_stripe_size`?
