All users know how sluggish and laggy Ria OLAP grid runs as soon as the grid gets larger than a few rows/columns.
There should be the possibility to speed the grid up by using Silverlight 3's feature of handing the load of rendering the GUI to the GPU (graphics processing unit) instead of to the CPU.
I urgently request to take a look into this possibility, because Ria OLAP grid is almost unbearable unperformant.
