The issue is that the performance of the new QSR is very slow in comparison to the old QSR.
The INSERT script has 40K UPDATE statements.
In the new QSR, it was doing about 100 Lines per 3 minutes.
In the old QSR, it was doing several thousands of lines in a minute.
This is due to the the Unicode support that's slowing things within the QSR.
Very little can be done except perhaps to send their inserts as an anonymous block instead.
