If there is no change in the application, I'm expect this to be normal. The biggest change in QV12 is that it uses the same QIX Engine than Qlik Sense, which is not just an upgrade rather a rewrite-to-improve of the original Associative Engine (the one used in QlikView 11 and previous versions).

Try to make your tables wider by joining tables and review your expression syntax, also check Qlik Support knowledge base for tips and hints on how to adapt QlikView 11 applications for better performance in QlikView 12/Qlik Sense.
