Hello everybody,

Did enybody else notice that there is a huge performance difference between a TreeViewer and a TableViewer (TreeViewer is much more faster).
I have a Table containing CellEditors (with EditingSupport) with about 30 columns and when I'm scrolling it, especially horizontally, it's very slow. Also multi cell selection is slow too.
I changed the table to a Tree (just changed the main TableViewer to a TreeViewer and the specific classes) and there is a huge performance gain.
Why is this? Is this fixed in newer versions of eclipse or should I just migrate my table to a tree with no children?

P.S. I'm using SWT and JFace 3.7 on win7.

Thanks in advance.
