I don’t know your design, but 9000 kerning pairs sound quite a lot. You might need to improve your spacing before you start kerning. And do you use groups/classes?
I have a similar problem, my font contains several writing systems so I really do need to have lots of kerning. How can I sort out the problem? Mine says 3 Type: PairAdjustment.
I already compressed the kerning and I have everything in classes.
How can I extend the kerning, thank you very much,
