Layout Performance Question - Tab Control with Multiple Portals
I would like to have a main layout which has multiple tabs. Each tab will have a portal. So for example, I would have a "sales center" layout which has tabs: invoices, customer list, sales rep list, sales order list, etc.
The purpose is to have one main place for all sales related information. My only concern is performance and a slow loading layout because the layout would be loading so many portals.
Is this something to be concerned about? Should I separate the layouts so that each major section has it's own layout?
