The paging here is based on the collection of components in a page. The components for all pages are being loaded when the view is requested. Pagination is available out of the box from FreeMarker for grids but not for component collections. This will have to be done programmatically in Kuali or extend FreeMarker.
But this would provide a very large performance boost. The Lab Performance view has been tested with this theory and it looks like true server side paging would then make every page load at the same rate regardless of the number of components needed. It would also cut down on the number of objects being stored in memory, which will cut down on memory consumption.
