Consider using scalable forms when
Administrators are manually editing users who have many resource accounts. Implementing a scalable form under these circumstances allows administrators to selectively edit specific resource accounts without incurring the overhead of fetching the user’s data for all resource accounts. This mechanism is particularly useful when a certain type of resource responds much slower than the other resource types associated with a user.
Custom provisioning processes, such as ActiveSync, target only specific resources for updates
Do not use scalable forms when form logic includes attributes that reference other resources. In this configuration, these cross-reference attributes will either not be populated with the latest data, or these resources should be fetched together.

In addition, the scalable version of the Create User form provides limited benefit over the standard default version because a new user has no resources to begin with.
