I am trying to copy objects b/w s3 buckets using S3 batch operation. Both buckets are in same region but different account. I followed this blog and set up the inventory/role/policies.
I found that S3 batch operation is dead slow. Below is my source bucket stats:
Bucket size: 2.7 TB.
Number of objects: 169 Million
In 14 hours, it copied only 20% objects
Any help is really appreciated.
