Recently I've started to use Secrets Manager to read credentials from Lambda, and I noticed that reading a secret from SM takes several seconds. Introducing VPC interface endpoint as described here: https://docs.aws.amazon.com/secretsmanager/latest/userguide/vpc-endpoint-overview.html#vpc-endpoint didn't help, I see the same response time.
In CloudTrail I see that created VPC endpoint is used to call Secrets Manager.
Did anyone have similar issue?
