Lazy loading is a technique for lowering memory consumption and, possibly, processing time. This technique delays the loading of data until the moment when it's actually needed in the UI. For example, if you have a Grid component with, say 10,000 rows, only a bunch of them are visible at a given time. Loading the full set of 10,000 rows might be a waste of resources.
