    AdvancedDataGrid slow


      Hi all. I'm attempting to use AdvancedDataGrid in a vanilla manner, but the performance is quite slow and consumes around 70% of one core on my cpu. The performance seems to go down in proportion to the number of visible cells. To see where time was being spent I extended AdvancedDataGrid and added a trace around the updateDisplayList. For me it takes about 250ms for each call to complete when 31 columns and 44 rows are visible, regardless of how many cells actually change, as long as at least one of the cells' contents changes. Scrolling is also quite slow and takes 1 or 2 seconds to see an update. Any suggestions ?
