Label are documented to be relatively heavy on the scenegraph, and it shows when displaying a trace with a high number of threads. Using Text items instead makes the scrolling blazing fast, but Text doesn't have as many pretty-printing capabilities.
The ideal solution would be to move to a ListView, or even TreeView right away. Those only fetch and render data as needed. However those are more complex Controls, and as such they probably wouldn't need a ScrollPane on the tree side to hold them. Some refactoring would be involved.
