Rationale
Using multiple apex:form
in your page or component causes multiple instances of the view state to be created for your page or component, making it much more likely to hit view state limits.
Scope
Visualforce pages
Visualforce components
Keep the size of the Visualforce view state lean, in order to minimize loading times and avoid hitting governor limits.
