Verification slow-down on upgrade to 0.8.4-1

After upgrading from 0.7.3 to 0.8.4-1 I have had a dramatic slow-down in the verification of the repo. from minutes to hours. I didn’t change any setting in my policy or percentage setting (5%) to verify.
The first maintainance seemed to delete a large part of the snapshot repo then rebuild it on the first backup but the verify time hasn’t improved. So I’m not sure what to make of that or whether there is anything I can do to improve it.

Did it finish the verification? How long did it end up taking?

Can you run and time kopia snapshot verify and kopia content verify ?
Also can you share kopia content stats and kopia blob stats ?
