Hi Bogdan,
In 12.2 we added more input verification and deepened inheritance checks that do take more time. The approach here was focused on completeness, and in the future we are hoping to look into speeding up these checks.
As we discussed in our email exchange and in your other recent post, we are covering more types of value setting with more consistency, with the scope in 12.3 being much wider in relation to what was available in 12.1.
Let us know of any other issues you may find.
Sergio
