More numbers: The patch reserves 67 buckets in the QHash table vs. 37 by default. In my test, pasing the content of https://www.boe.es/legislacion/documentos/ConstitucionCASTELLANO.pdf from Okular, the number of items in the cache is a maximum of 24 members when inserting. But the first undo uses up to 2300 members (4099 buckets), and later undoes only use a maximum of 43 members. The performance problem is in the first undo. What could be the difference between the first undo and subsequent undoes?
