Bug 565061 - faster deletion in TreeViewer.removeAll() Looking at the test Bug548982_TreeAddRemoveMany.java. Without this change I get CreateTreeItems: 3437 ms DeleteTreeItems: 8980 ms CreateTreeItems: 3576 ms DeleteTreeItems: 9065 ms With this change CreateTreeItems: 3326 ms DeleteTreeItems: 2729 ms CreateTreeItems: 3276 ms DeleteTreeItems: 2739 ms In tests with less than 20-30 elements of treeview switching off redraw in removeAll() method does not have a clear advantage. Times measured are fluctuating strongly. So to be on the safe side only do this for more than 30 elements.
