In Oct 2024, delivered a targeted frontend performance improvement by refining the Tree component to avoid sending unnecessary 'nodesChecked' events to the server. Introduced a new method _processTreeCheckNodesResult to handle rendering and event triggering only when there are actual nodes to report and when the tree is checkable, reducing server load and improving performance. This work minimizes server round-trips and enhances UI responsiveness for tree interactions.
