Hello,  The Data Manager app does not have a limit on the total number of data accounts that can be onboarded in a multi account input. Please share some more details on where the slowness of the app is being observed for 30 accounts or more? Is slowness is on the app (UI) or on the data ingestion side or on the template deployment ?  Please note that some API's are expected to take more time depending on the total number of accounts and regions since the app will query AWS API's from all these accounts and regions. Hence there will be little lag on the UI when viewing input details.  The AWS CloudFormation deployment time depends on the number of accounts and regions the stack set is deploying and it is not related to DM app.  If you already have centralized logging accounts for CloudTrail, GuardDuty, IAM and Security Hub, then it is best to onboard just those accounts since you don't have to go through setting the pre-requisites in all of your data accounts. ...
