Hello Wu,
This seems to be a known issue that is already logged on our feedback portal. You can track its progress, subscribe to status changes, and add your comment to it here: SyntaxEditor: XmlFolding tagger is slow and UI freezes in XML documents with thousands of lines.
Let me know if I can assist you further.
Regards, Dimitar Progress Telerik
