AWS Cross Account Latency while accessing DBs

Question

Would there be any latency in accessing data from S3 bucket if move my bucket to another AWS account for security reasons??

I have a service that runs in an AWS account and it uses S3 bucket from the same account. Now, I would like to move my S3 bucket to another account to segregate my service and resource tiers for security reasons. Would this change cost me any latency issues as I would be using assuming roles and going from one vpc and security group to another?

Within the same region the short answer is no, there would be no added latency or other performance impacts. This is a very common use pattern, and all applicable S3 performance guidelines will still be in effect. Assuming a cross-account role or referencing a principal from another account would not introduce additional latency.
